Wednesday !!! PLACE: Building 26, Room 112 (first floor) !!! TITLE: Circular Bragg nano-Cavities: Beyond the limits of total internal reflection SPEAKER: Dr Koby Scheuer, California Institute of Technology (Caltech) ABSTRACT/COMMENTS: NOTE CHANGE OF DATE/TIME Wednesday, January 05, 2005 AT 1500,AND PLACE (Building 26, Room 112 (first floor))!!! Circular resonators are key ingredients in the realization of basic components required for advanced optical communication systems as well as for biochemical sensing and basic research. The important characteristics of a ring resonator are the Q-factor, the free spectral range (FSR) and the modal volume, where the last two are primarily determined by the resonator dimensions. The Total-Internal-Reflection (TIR) mechanism employed in “conventional” resonators couples between these characteristics and limits the ability to realize compact devices with large FSR, small modal volume and high Q. In this talk, a new class of circular resonators, which is based on radial Bragg reflection, is reviewed. The radial Bragg confinement breaks the link between the characteristics of the mode and paves a new way for the realization of compact and low loss resonators. I will present the design rules as well as fabrication and characterization of various types of circular resonators of this c lass and discuss their advantages for various applications especially in sensing and telecommunications.

We concentrate on the U(N) singlet sector of these models. In the particular case of quadratic matrix potential, the singlet sector can be mapped by a similarity transformation onto the two-dimensional Calogero-Marchioro-Sutherland model at specific couplings. For this quadratic case we were able to obtain infinite sets of singlet eigenstates of the matrix model, one of which (and its complex conjugate), we believe, were hitherto unknown in the literature. Our main object in this paper is to study the singlet sector in the collective field formalism, in the large-N limit. We obtain in this framework the ground state eigenvalue distribution and ground state energy for an arbitrary potential, and outline briefly the way to compute bona-fide quantum phase transitions in this class of models. As explicit examples, we analyze the models with quadratic and quartic potentials. In the quartic case, we also touch upon the disk-annulus quantum phase transition. In order to make our presentation self-contained, we also discuss, in a manner which is somewhat complementary to standard expositions, the theory of point canonical transformations in quantum mechanics for systems whose configuration space is endowed with non-euclidean metric, which is the basis for constructing the collective field theory.

Recent evidence has indicated that necrotic cell death could be related to intrinsic cellular mechanisms, and thus human cell death can be understood as a process that can be approached. Morphological manifestations and biochemical pathways involved in cell death and the relevance to disease will be described. We will also present our studies which concentrate on two fields of research related to cell death. One focuses on the role of serine proteases especially in necrotic cell death and the use of their inhibitors for its prevention, and the other attempts to search for drugs that kill cancer cells by induction of apoptosis and investigates the mode of action of the drugs. The application of the experiment al results to clinical practice will be described as well.

The ‎Physics of the correlators and the fluctuation-dissipation theorem ‎will be explained. The generalization of the latter to steady ‎nonequilibrium states will be discussed. Brief remarks will be made ‎on fundamental constraints on amplification in the quantum ‎domain. ‎ One of the most interesting consequences of the quantum ‎fluctuations is the Casimir force, due to the radiation pressure of ‎the electromagnetic “vacuum”. Contrary to existing results, it will ‎be shown that this pressure is negative. An (in principle) ‎straightforward experiment is suggested to confirm that. Both ‎macroscopic and nanometer-scale aspects of the effect will be ‎discussed, along with insights on the subtle questions related to ‎the Casimir effect. The substantial Casimir pressure on a thin ‎conducting film, due to surface plasmons, will be demonstrated.‎ From nano at bgu.ac.il Tue Feb 15 21:51:28 2005 From: nano at bgu.ac.il (Nano) Date: Tue Feb 17 13:18:16 2009 Subject: [Phys-seminars] 2005-02-23 nanotechnology workshop Message-ID: <001d01c51397$bd5b8bd0$1b0e4884@estinano> Nanotechnology workshop, Wednesday February 23, 12:00 Chemistry Department seminar room (building 29, room 306) refreshments will be served starting 11:45 Title : Dendrimers: An Introduction for Nanotechnologists Speaker: Andy Shipway Casali Institute of Applied Chemistry The Hebrew University, Jerusalem -------------- next part -------------- An HTML attachment was scrubbed...

Dan Mishmar, National Institute of Biotechnology Department of Life Sciences ABSTRACT/COMMENTS: Mitochondria were incorporated into ancient Eukaryotes to utilize oxygen in energy production more than a billion years ago, resulting in a far more efficient cellular energy (ATP) production. As a by-product of cellular energy production, the mitochondrion also produces Reactive Oxygen Species (ROS), the cumulative damage of which is implicated in aging. Previously it has been shown, that mitochondrial DNA linked sets of common variants (haplogroups) are associated with age related disorders. In contrast, it was also shown that mitochondrial DNA common variants are associated with prolonged aging. We have shown that such common variants associate with adaptation of humans to different climates. In this seminar we shall discuss these apparently contrasting roles of mitochondrial genetic variability in human life.

Don\'t forget to come. Refreshments are served at 3:20pm Abstract: We describe an experimental demonstration of fast magnetic-field penetration into a low-collisionality plasma. Remarkably, field penetration and plasma reflection are found to occur simultaneously. This results in ion separation. It also allows for the understanding of the magnetic-field-energy dissipation channels. The light ions, even being a minority, are seen to acquire most of the field energy and momentum. Observaions of ion reflection at more than twice the magnetic field velocity will also be discussed.

The experimental study of nonlinear electrodynamics show that large nonlinear response of a single crystal ZrB12 to an ac field (frequency 40 - 2500 Hz) exists for H0>Hc2. Direct measurements of the ac wave form and the exact numerical solution of the Ginzburg-Landau equations, as well as the phenomenological relaxation equation, permit the study of the surface superconducting state dynamics. It is shown, that the low frequency response is defined by transitions between the metastable superconducting states under the action of an ac field. The relaxation rate which determines such transition dynamics is found.

This theory is an extension of the Redfield theory to situations where energy conservation of the total system is crucial. We verify the validity of this theory on the spin-GORM model (two-level subsystem interacting with a random matrix environment). We finally present the study of a finite periodic tight-binding chain interacting with its environment. We show that quantum diffusion arises when the size of the chain becomes larger than a critical size.

As the induced perturbation becomes larger, there is a crossover from a perturbative to a non-perturbative regime, which is reflected in the structural changes of the local density of states. For the first time the full scenario is explored for a physical system: an Aharonov-Bohm cylindrical billiard. As we vary the magnetic flux, we discover an intermediate twilight regime where perturbative and semiclassical features co-exist. This is in contrast with the simple crossover from a Lorentzian to a semicircle line-shape which is found in random-matrix models. The resulting structures can be understood using a phase-space picture, and are related to the non-semiclassical features of the wavefunctions. In other words, on the one hand we demonstrate the limitations of random matrix modeling, while on the other hand we show the consequences of having failu re of the so-called “Berry conjecture”.

The experimental system consists of optical tweezers and micron sized beads that are tethered to the bottom of the sample via single DNA molecules. The beads lows down the DNA relaxation from a strongly stretched configuration such that it is passing only through quasi-equilibrium states. This allows for a theoretical description of the relaxation trajectory which is in good agreement with experiment.

For example, the density of particles in a system may be specified by either the chemical potential (?) or the overall number of particles (N). A straightforward functional generalization of the Legendre transform allows one to determine the spatial distribution of a system of electrons by specifying the density distribution n(r) rather than the external potential v(r). This will be used as the basis for an alternative derivation of DFT at finite temperatures T [convexity arguments can then be used to prove that for finite temperatures a on-to-one relationship exists between v(r) and n(r), i.e. there is no v-representability problem]. The usual ground-state DFT will then be obtained in the limit of vanishing temperature. This alternative point of view sheds light on the Hohenberg-Kohn theorems, the Kohn-Sham equations, and the nature of the exchange-correlation energy. This lecture is a continuation from last week. ? -------------- next part -------------- A non-text attachment was scrubbed...

The origin of the anomaly can be traced to the development of a Kondo effect due to the formation of a local magnetic moment in the vicinity of a QPC. I will present density functional theory (DFT) results that show that under certain conditions, a local moment indeed forms on top of a QPC. First, I will consider a simpler problem of electrons in a quantum wire of infinite length. I will describe in detail the numerical implementation of Kohn-Sham equations within the local spin density approximation (LSDA). I will discuss the calculation of the Hartree and exchange-correlation potentials, the self-consistent determination of spin density and the calculation of the ground-state energy. The results of this calculation show that if the density of electrons in the wire is low enough, a spin-polarized solution of DFT equations appears which has a lower energy than the unpolarized solution. Then, I will formulate the Kohn-Sham equations for a QPC and describe the methods employed to solve them. Finally, I will briefly discuss the results of the calculation. -------------- next part -------------- A non-text attachment was scrubbed...

Bliokh, Institute of Radio Astronomy, Ukraine ABSTRACT/COMMENTS: Semiclassical evolution of relativistic particles in external potentials is considered. In adiabatic approximation, evolution of each energy level is characterized by its own Berry gauge field. For massless particles, it has the form of magnetic monopole in the momentum space origin. For massive particles, it is a non-Abelian field. This results in non-commutativity of coordinates and appearance of additional terms (‘topological force’) in the equations of motion. We derive the semiclassical motion equations for relativistic electron in an external electromagnetic field. The Berry gauge potential is responsible for the spin-orbital interaction of the electron. However, we show that the electron moves along trajectories, essentially different from those predicted by traditional theories. In particular, the deflection of an electron moving along the electric field is two times larger, than that caused by conventional spin-orbit interaction in Pauli Hamiltonian. We examine also the semiclassical evolution of photons in an inhomogeneous dielectric medium. In Maxwell equations, Berry gauge potential results in similar ‘spin-orbital interaction’ accompanied with various phenomena like ‘spin Hall effect of light. This leads to the effect, which is absent in the traditional geometrical optics, namely the refraction becomes dependent on the wave polarization.

In this study a high-throughput method for cultivating uncultured majority of microorganisms was developed. Rationale of the method was to encapsulate bacteria in agar sphere than coating it by polysulphone membrane which is permeable, that allowed nutrients and other environmental chemicals to enter the sphere but prevented the bacteria from escaping. At those conditions previously uncultured microorganisms induced ability to grow in community or as pure culture. Furthermore, subsequent 16S rDNAs sequencing of the spheres displayed novel bacteria and high microbial diversity of the environmental samples.

Gheber, Department of Biotechnology Engineering Ben-Gurion University of the Negev ABSTRACT/COMMENTS: The definition of nanotechnology depends in part on who\'s doing the defining. Within industry, anything less than a micron is considered \"nano\" while the National Science Foundation defines nanotechnology as \"the ability to manipulate individual atoms and molecules, making it possible to build machines on the scale of human cells.\" Biology has been nano from the get-go. All organisms, from microbes to humans, are powered by highly evolved molecular and cellular machines that operate at the nano level. The more we learn about these naturally occurring nano machines, the closer we come to engineering new ones with different functions. This convergence of technology with biology at the nano level is called nanobiotechnology. (Robert Elde, Dean, the College of Biological Sciences at the University of Minnesota). Whatever the definition, it is becoming clear that that the pure “bottom-up” approach to nanotech is not sufficient. Self-assembly and recognition are the basics of the bottom-up strategy, whereby following smart design of the building blocks, they self assemble in the correct order and positions, to give birth to the desired device. However, it is nearly impossible to control such processes in three dimensions, and all the examples shown so far are two dimensional (at the most). The combination of bottom-up with top-down strategies should ultimately provide the sought solutions. The natural toolbox of the nano(bio)technologist includes the scanning probe microscope, which is a “two-in-one” tool: it can provide images with nanometer resolution, but it can also modify the sample with the same precision. We are developing SPM based techniques to tackle some of the problems related to nanobioelectronics, nanobiochips and lab-on-a-chip areas. We will present a number of examples demonstrating the power of SPM tools, including imaging, printing, etching and measuring forces of/by biological materials.

These breakthroughs have been primarily driven by three factors: 1) Rapid advance in the manufacturing technology of double-clad fibers, which enabled the emergence of large mode area (LMA) fibers with specially designed doping profiles, 2) progress in the development of high brightness pump diode lasers and 3) efficient and robust high power coupling methods between the diode laser pump source and the lasing fiber. By utilizing LMA double clad fibers, non-linear detrimental effects can be avoided and high beam quality can be achieved by spatial filtering of high order LP modes without jeopardizing the optical efficiency of both CW and pulsed fiber laser devices.

The properties of locations in the vortex lattice and their distinctions from those in atomic solids will be discussed. 2) The effect of the zero-field (vortex annihilation) lines on the flux dynamics will be analyzed. It will be shown that the presence of annihilation lines lead to significant retardation of the flux motion in the whole sample.

Bldg. 29 Room 306 Title: Introduction to Time-Dependent Density functional Theory Professor Roi Baer Hebrew University of Jerusalem Abstract: A short introduction to time-dependent density functional theory (TDDFT). We start by reviewing the time-dependent Schrodinger Equation, the evolution operator, including the TD variational principle of quantum mechanics. We then present the basics of the TDDFT approach to many particle systems, based on the Kohn-Sham theory and the Runge-Gross theorem. We then introduce the adiabatic local density approximation and discuss some of its successes and failures. We give a flavor of new approaches to TDDFT that try to improve the accuracy and scope of TDDFT. Finally, a particular numerical method of application of the theory is discussed in some detail. Several recent applications of the theory within this approach are surveyed, including application to molecular electronics, strong laser-molecule interaction and the Ehrenfest molecular dynamics approach to processes where the Born-Oppenheimer approximation is known to fail. Note: This will be a long seminar. Refreshments will be served before and during the seminar. -------------- next part -------------- A non-text attachment was scrubbed...

I will present a model in which the redox chemistry of these cofactors is suggested to play a role in scanning the genome for chemically modified bases by a DNA-mediated electron transfer process. First, I will show that an electron originating from the [4Fe4S] cluster can be trapped in a DNA-mediated reaction and then I will show evidence that the redox activation of these cofactors is triggered in DNA in-situ by guanine radicals.

Although on a thermodynamic basis, single-stranded DNA binding proteins should lower the thermal melting temperature of double-stranded DNA (dsDNA), gp32 does not. The problem of the interplay between the dynamics of local DNA denaturation zones and the binding of these proteins is potentially biologically significant because uncontrolled helix-destabilization would be lethal to the cell. Motivated by results from recent single DNA overstretching experiments, we model the binding of proteins to fluctuation DNA-bubbles, obtaining a quantitative picture of the process: depending on the known parameters of the proteins, they modify the free energy landscape of the coupled bubble-protein process. In an extreme case, binding proteins can indeed induce full DNA denaturation.

As an exciting new application we show that the technique allows for the detection and theautomatic correction of some errors in the genetic code by purely optical means. This is exemplified by considering the repair of mutations caused by a double proton transfer between two hydrogen-bonded nucleotides kept at inter-nucleotide distances typical of the DNA double helix. We show how coherent control, in conjunction with adiabatic passage, allows one to detect the error and automatically repair it as it is being detected, by converting a mutated pair to the non-mutated one.

Further exploration of the interplay between spin and orbital degrees of freedom in the Kondo effect became possible in experiments with double dot systems. If the two dots are strongly electrostatically coupled, then there are regions in the charging diagram of the double dot device, where there is no energy cost to transfer an electron between the two dots. In that regions, the two ground states of the double dot system with occupations of the two dots (N1-1, N2+1) and (N1, N2) are degenerate. The two ground states build a two-dimensional Hilbert space which spans the representation of the SU(2) group, hence a spin-like degree of freedom called pseudospin can be assigned to those two states. Quite analogously to and to a large extent independently of the well-known spin Kondo effect, the orbital fluctuations in transport through the double dot result in the development of the orbital, or pseudospin Kondo effect. Furthermore, at special values of Kondo couplings, the combined spin and pseudospin Kondo Hamiltonian possesses a SU(4) symmetry with respect to rotations in the spin-pseudospin space. In that regime, the SU(4) Kondo effect with greatly enhanced Kondo temperature has been predicted theoretically.

These dynamic changes are governed by the activity of microtubule-based kinesin-related molecular motor proteins, which use ATP hydrolysis to unidirectionally move along microtubules. Our work focuses on the function of the S. cerevisiae motor protein Cin8p from the BimC family of kinesin-related proteins. The members of this family are found in all eukaryotes and perform similar essential roles in all stages of spindle dynamics. It is believed that BimC motor proteins perform their functions by virtue of their motor activity, i.e. by binding to and moving along microtubules. However, mechanisms by which BimC proteins these functions and how their activity is regulated are still unknown. In order to address this issue, we apply a number of microscopy-based in vitro and in vivo assays to study Cin8p activity and regulation. In the in vitro assays we study Cin8p motor activity, i.e. its ability to bind and move microtubules. We express a biotinated version of Cin8p (Cin8p-BCP) in S. cerevisiae cells and study its activity in cell lysates on an avidin coated surface. The power of this approach is to be able to follow Cin8p activity as a function of the cell-cycle. Our results indicated that the ability of Cin8p to bind microtubules changes as a function of cell-cycle progression and as a function of Cin8p phosphorylation state. In addition, we analyzed in vitro activity of Cin8p motor domain mutants and studied the consequences of these mutations on Cin8p mitotic functions in vivo. In in vivo assays, we examine the spindle dynamics by immunofluorescence and in real-time, following the fluorescence of GFP-tagged spindle components. We found that Cin8p binding, but not motility is important for spindle assembly, while both motility and binding are important for anaphase B spindle elongation. We suggest that Cin8p performs its mitotic functions by changing its motor activity during mitosis and that this change in activity is regulated by Cin8p phosphorylation.

GGA and hybrid GGA functionals will often predict barrier heights that are too low by several kcal/mol which corresponds to reaction rates that are too high by several orders of magnitude. Indeed, for some hydrogen transfer and SN2 reactions, GGAs or even hybrid GGAs may falsely predict a barrierless transition. (Contrary to popular belief, the problem is not limited to hydrogen transfers.) A stop-gap solution consists of artificially increasing the percentage of HF exchange to the 40-45% range: "kinetics" functionals such as mPW1K thus render fairly reliable barrier heights, at the expense of severely degraded performance for other properties. We found that this problem can be surmounted if a flexible hybrid meta-GGA form (involving the kinetic energy density) is combined with a high percentage of HF exchange, and all parameters are self-consistently refined against a large set of thermodynamic, structural, and kinetic data. The resulting functional, BMK (Boese-Martin for kinetics), is no longer an ad hoc "kinetics" functional but a general purpose functional whose realm of applicability has been extended to kinetics.

A detailed understanding of the microscopic processes governing the electronic response, as well as guidance in the search for new molecular assemblies with large nonlinear response properties, can and should come from theory. Unfortunately, this electrical response is dramatically overestimated by density functional theory (DFT) with either local or semilocal density functional approximations. Here, we show that DFT does yield accurate linear and nonlinear polarizabilities when the exact exchange energy is employed together with the corresponding exact Kohn-Sham potential. We further show that approximations that are very accurate for the ground-state energy can nevertheless fail badly for the response because of potential barriers that have little effect on the ground-state energy but strongly affect the electron mobility. We discuss the implications of these findings to further development of orbital-dependent functionals as a means of attacking problems traditionally considered as ?too difficult for DFT?. -------------- next part -------------- A non-text attachment was scrubbed...

Boris Malomed Department of Interdisciplinary Studies, Faculty of Engineering, Tel Aviv University ? Abstract After presenting a general introduction to gap solitons in optics and matter-waves, we develop a coupled-mode theory for spatial gap solitons in one-dimensional photonic lattices induced by interfering optical beams in a nonlinear photorefractive crystal. Assuming a superposition of two counterpropagating waves, we arrive at a system of coupled-mode equations with a saturable nonlinearity (actually, one equation is linear). We construct a family of soliton solutions to this system, and identify their stability region (while all the solitons are stable according to the Vakhitov- Kolokolov criterion, inside their family there is a nontrivial border of stability against perturbations with complex eigenvalues). The soliton family is extended to include "moving" (actually, tilted) solitons; the stability border virtually does not depend on the tilt. Collisions between the tilted solitons are studied too, and conditions providing for elastic collisions are identified. -------------- next part -------------- A non-text attachment was scrubbed...

If the particles are advected with the fluid, this expectation is valid, but if the effects of their inertia are significant, the particles may cluster. This effect is analysed by determining the Lyapunov exponents of the particle trajectories. The Lyapunov exponents are determined as power series in a parameter which measures the inertia, by mapping the problem to a perturbation of a nine-dimensional harmonic oscillator. The results challenge a consensus that clustering only occurs wen the product of the viscous damping rate and the correlation time of the flow is a number of order unity. The talk reports joint work with B. Mehlig, S. Ostlund and K. Duncan.

It is shown that triple quantum dots (TQDs) with even electron occupation manifest a novel type of Kondo effect that has not been observed in magnetically doped bulk metals. If the low-lying spin excitations are properly incorporated, the exchange Hamiltonian of TQDs unveils unusual dynamical SO(n) symmetries instead of conventional SU(2) symmetry. These symmetries can be experimentally realized and the pecific value of n can be controlled by gate voltage. The responding o_n algebras are constructed and the Kondo temperatures are calculated. The hidden dynamical symmetry manifests itself in the existence of the Kondo effect in molecules with strong correlations and in the occurrence of non-universal Kondo temperature. The symmetry groups for a magnetic field induced Kondo tunneling are SU(2) and SU(3). We also elucidate the physics of Kondo effect and related phenomena in a triangular triple quantum dot (TTQD). Such nano-object can serve both as a Kondo-scatter and as a peculiar Aharonov-Bohm interferometer where the magnetic field affects not only the electron phase but also the nature and degeneracy of its ground state. The Kondo physics in TTQD is determined by a subtle interplay between continuous spin rotation symmetry SU(2), and discrete \"crystal\" point symmetry C_{3v}.

Chemical Engineering, Technion Abstract We present a study of wetting phenomena based on the density functional theory. The focus is mostly on the impact of long-range van der Waals interactions both within the fluid and between the fluid and substrate. For the latter, we consider two models-hard wall and soft wall approximations - differing by the role of steric effects and leading to a qualitatively different character of phase transitions. We compute numerically the disjoining potential (which is important dynamically for spreading, spinodal dewetting, and coarsening in thin films, as well as resolution of interfacial singularities), and loci of intermediate and complete wetting transitions as functions of the Hamaker constant and temperature. We find that taking into account short-range interactions is essential for the description of wetting transitions in the soft wall limit. We derive an analytical form of the disjoining potential and analyze it in the context of the complete, frustrated and partial wetting. -------------- next part -------------- An HTML attachment was scrubbed...

SPEAKER: Professor Tai Kai Ng, Department of Physics, Hong Kong University of Science and Technology Guest professor at Phys. Dep. BGU August 10-20 2005 (host - Yshai Avishai) ABSTRACT/COMMENTS: A general transport equation for the center of mass motion is constructed in order to study transport of electronic system under uniform magnetic field and microwave radiation. It is them applied to study 2D electron system in the limit of weak disorder. Instabilities in the system at strong enough microwave radiation are identified and a solution of the transport equation with spontaneous AC current is proposed to explain the experimentally observed Radiation-Induced Zero Resistance State.

This Ehrenfest-time is the time in which a minimal wave packet is stretched to the system size. When this Ehrenfest-time is larger than the typical dwell time of electrons in a cavity the transport is expected to be \"more classical\". The behavior of weak localization, conductance fluctuations and shot noise in this limit has attracted a lot of interest recently. In particular, a phenomenological model which was suggested to describe numerical results disagree with semiclassical calculations, which predicted suppression of weak localization with the Ehrenfest-time. We resolve this puzzle by modifying both theory and numerics. The semiclassical theory is modified to include classical correlations which were not taken into account previously. Numerical results, with improved accuracy, agree with this semiclassical theory. However, the numerical results for conductance fluctuations are puzzling.

The environmental degrees of freedom constitute a bath. Some of the bath modes cannot be excited by the particle and induce the so called \"zero point fluctuations\". We discuss the effect of these modes on the dissipation process using a scattering approach. We are going to show that the ZPF modes may enhance the inelastic scattering and hence indirectly contribute to the dephasing process. [MA seminar].

These can be created either directly using high spatial resolution potentials from structures on the atom chip, which requires atom-surface distances of the same the order of a few m, or by employing adiabatic radio frequency (RF) or micro wave (MW) potentials. In both cases this necessitates to have very smooth potentials and very strong transversal confinement in the order of ~10kHz which leads to 1d traps with extreme aspect ratio up to >1000. We experimentally investigate manipulation of cold thermal atoms and BEC’s in this parameter range. Using lithographically fabricated atom chips, we suppress previously observed large disorder potentials by many orders of magnitude [3]. This allows to create 1 dimensional Bose-Einstein condensates on the atom chip which can be used to study magnetic and electric disorder potentials with a resolution to better than 10^-13 eV, competitive with the magnetic field sensitivity of SQUIDs [4]. In these smooth atom chip traps we used RF induced adiabatic potentials to split a 1d condensate along its long axis. Bringing the two split clouds together we can measure the interference between the two ensembles and study the coherence in the atom manipulation process [5]. The prospects of these RF and MW induced potentials for quantum information processing will be discussed [6]. [1] For an overview see: Microscopic atom optics: from wires to an atom chip.

Current estimates require errors smaller than 10-2. In this talk I will review recent progress in trapped-ion quantum information processing towards achieving such operation fidelities. A memory coherence time exceeding 10 seconds was measured. This time is 107 times longer than the time required for for a single qubit quantum gate. Laser-assisted qubit manipulation errors due to the spontaneous scattering of photons were investigated. It is shown that with sufficient control over laser parameters this error can be arbitrarily small. Laser parameters which imply an error of 10-5 in a single qubit rotation are demonstrated.

Box 9001, Beer- Sheva, Israel ABSTRACT/COMMENTS: The use of polarized Raman spectroscopy to determine the structure of single GaN nanowires (~120nm) will be discussed. The sensitivity of the Raman spectrum simultaneously to the relative orientation of the k-vector and electric-vector of the incident and scattered light with respect to the crystallographic axes of the nanowire will be presented. Because GaN nanowires absorb in the wavelength regime used, the Raman susceptibility tensor elements are complex-valued. This enriches the angle-dependence of the polarized Raman spectrum, allowing the relative phase among the Raman tensor elements to be determined. We combine an analysis of the effect of polarization with the secure geometrical knowledge obtained using high-resolution TEM.

These include slow relaxation, slow approach to a steady state, aging, and other memory effects that are common characteristics of other types of glasses. The typical relaxation time of this, so called electron glass, may be controlled by disorder, magnetic field, and carrier concentration. Due to the absence of metallic screening, the inter-electron interaction strength increases with the concentration of carriers, which in turn slows down the relaxation processes in this medium. Interestingly, in contrast with most other glasses, the system dynamics does not slow down upon cooling below a ‘glass-temperature’, a feature consistent with the behavior expected of a quantum glass.

Koch, 1Department of Physical Chemistry and The Fritz Haber Research Center, The Hebrew University, Jerusalem 91904, Israel 2Laboratoire Aim´e Cotton, CNRS, Bˆat. 505, Campus d’Orsay, 91405 Orsay Cedex, France ABSTRACT/COMMENTS: The creation of ultracold molecules and molecular Bose-Einstein condensates open the way to study novel collective phenomena and ultracold chemistry. The enormous progress achieved in recent experiments inspired the present theoretical work on new possibilities to coherently manipulate ultracold matter. In the talk, three different proposals for the interaction of lasers with ultracold matter will be presented. First the creation of molecules from pairs of ultracold atoms in a tightly confined Bose- Einstein condensate or Mott insulator state is suggested by adiabatically crossing an optical Feshbach resonance. This corresponds to tuning both intensity and frequency of a CW laser. Calculations were performed for 87Rb atoms. For sufficiently tight traps, up to 50% of the atom pairs can be transferred to the last vibrational level of the ground state.

From one side the connection between respiration and brain\'s blood flow, and from the other side its relation to the ECG signal. Among the parameters influencing brain\'s blood flow, special importance has the partial arterial pressure of CO2 , which is the most dominant one. Changes in its level can change to large extent the human physiology. We have developed a mathematical model which describes the blood flow as a function of PaCO2. The model is advantageous compared to other models in that it is simple, with four parameters which have a clear physical meaning, and with its aid it is possible to rescale results of experiments done on different animals to equivalent human ones. In order to increase the level of PaCO2 , which was measured with the aid of a Capnometer, we have developed simple breathing exercises allowing a significant increase in PaCO2 and in this way to increase brain\'s blood flow. In the numerous experiments performed in Prof. Heimer\'s laboratory we have succeeded to demonstrate that indeed this task can be achieved by relatively simple means. Respiration influences the heart\'s electrical activity, which can be seen in the RR intervals of the ECG and analyzed by spectral analysis characterized by the appearance of the High Frequency (HF) pick related to respiration rate. On the basis of our measurements we have found additional relations between respiration and the ECG signal. We have found that the height of R has wave properties, which follow nicely the respiration. In the spectral analysis of the height of R, only the HF pick appears and it is very distinctive. Therefore this analysis has the advantage over the RR spectral analysis in that the result is more distinctive and cleaner.

Petrov, QUANTOP, Danish National Research Foundation Centre of Quantum Optics, Niels Bohr Institute, DK-2100 Copenhagen Â, Denmark. ABSTRACT/COMMENTS: We present a method of nondestructive characterization of optically trapped atomic sample which relies on optical phase-shift measurement in a shot-noise-limited Mach-Zehnder white-light interferometer. The phaseshift imposed on an off-resonant light due to dispersive interaction with about 10^5 atoms is monitored by the interferometer, characterizing the dipole trap loading and loss dynamics, tem- perature, and oscillation frequency. The estimated rate of real transition for a single probe pulse is found to be as low as 0.038 photons per pulse. The real time monitoring of the phaseshift in a Mach-Zehnder interferometer allows for fast and nondestructive characterization of atomic samples. The pulsed homodyne detection scheme enables monitoring of processes and phenomena taking place in the atomic cloud on a microsecond timescale.

The common practice is to calculate the response (rate of energy absorption, conductance) using the Kubo Formula. We argue that this may lead to a huge over-estimate. In general it is essential to take into account the structure of the perturbation matrix, which may imply percolation-like dynamics. These structures are determined by both semiclassical and random matrix theory consideration, and cannot be ignored.

Gedalin on the structure of Saturn\'s rings. Abstract: With the Saturnian rings, which have been known for about four centuries, the Uranian, Jovian, and Neptunian rings form a new and interesting class of objects in the Solar System; they were discovered and extensively studied between 1977 and 2004. In this talk I review the basis of the physics of Saturn\'s rings. The observations of the smoky golden Saturn and its rings are discussed. The theoretical model is presented which explains both the origin of the rings and the fine-scale irregular stratification of the Saturnian ring system. The prospects for future studies are made as well.

For a three dimensional lattice we predict a sharp transition at a critical interaction strength beyond which the current is dynamically unstable. In one and two dimensions on the other hand, quantum phase slips induce significant current decay well before the critical interaction strength is reached, leading to broadening of the transition.

This leaves an unknown frontier, from redshift 6 up to 1000, during which the first galaxies formed and subsequently heated and ionized the cosmic gas. Several international efforts are underway to measure fluctuations in the redshifted 21cm emission from neutral hydrogen at these redshifts. We show how this new observational probe can be used to reveal much about physics in the early universe as well as previously unobserved astrophysical epochs. In particular, we introduce a new source of fluctuations that is currently the most promising way to detect and study the earliest galaxies.

Using angle resolved photoemission spectroscopy, we show that the anisotropy of the pseudogap in momentum space and the resulting arcs depend only on the ratio T/T*(x), where T*(x) is the temperature below which the pseudogap first develops at given doping, x. In particular the arcs collapse linearly with T/T* and extrapolate to zero extent as T does to zero. This suggests that the T=0 state is a nodal liquid, a strange metallic state whose gapless excitations are located only at 4 points in momentum space, just as for a d-wave superconductor.

A solution to this problem via passage through resonances and adiabatic synchronization will be discussed. The idea is based on capturing the system into persistent (auto-) resonance with a chirped frequency driving perturbation such that the driving amplitude exceeds a threshold. Among other applications, this approach allows efficient control of a classical state of Rydberg atoms in 3D, yielding gradual acceleration of the electron in the atom, until approaching the stochastic ionization limit. A similar phenomenon explains the Plutino puzzle of the early evolution of the solar system.

Theoretically, the simplest model featuring quantum phase transitions is the transverse field Ising model. Experimentally, the anisotropic dipolar compound LiHo_xY_(1-x)F_4 has been considered to be a realization of this model, with a possibility of displaying for x=0.167 a spin-glass to paramagnetic transition via a quantum critical point. Despite intriguing much of the recent theoretical interest in quantum spin glasses, some peculiar results in this experiment, as well as the nature of the observed transition, remained unclear. Here we discuss the significance of the hyperfine interaction in this system, and of the offdiagonal dipolar interactions in any dipolar Ising glass. We show that due to the latter, the application of any finite transverse magnetic field results in a finite correlation length and a destruction of the spin glass order in such systems. Our results naturally explain the experimental puzzles, as well as the nature of the quantum disordering of the spin-glass phase in dipolar Ising glasses.\" From physics at bgu.ac.il Wed Dec 21 11:07:35 2005 From: physics at bgu.ac.il (physics@bgu.ac.il) Date: Tue Feb 17 13:18:20 2009 Subject: [Phys-seminars] 2005-12-21 Astrophysics and Cosmology Seminar Message-ID: <200512210907.LAA63259781@tzin.bgu.ac.il> Astrophysics and Cosmology Seminar DATE: 21-12-2005 TIME: 12:00 noon (Wed) PLACE: Physics club (Building 29, room 002) TITLE: \"The Revolution in the Understanding of Short Gamma-Ray Bursts: Implications for LIGO\" SPEAKER: , Dr Ehud Nakar ABSTRACT/COMMENTS: From kletter at bgu.ac.il Wed Dec 21 12:11:25 2005 From: kletter at bgu.ac.il (kletter@bgu.ac.il) Date: Tue Feb 17 13:18:20 2009 Subject: [Phys-seminars] 2005-12-22 NLD seminar - reminder Message-ID: <20051221100439.84CD833E79@smtp2.bgu.ac.il> A Nonlinear Dynamics seminar on: Gradient Detection by Eukaryotic Cells: Spatiotemporal Dynamics to the rescue Speaker: Prof. Herbert LevineDepartment of Physics, University of California, San Diego Tomorrow, December 22 2005 at 11:00, the Physics club (room 002, building 29).

A solution to this problem via passage through resonances and adiabatic synchronization will be discussed. The idea is based on capturing the system into persistent (auto-) resonance with a chirped frequency driving perturbation such that the driving amplitude exceeds a threshold. Among other applications, this approach allows efficient control of a classical state of Rydberg atoms in 3D, yielding gradual acceleration of the electron in the atom, until approaching the stochastic ionization limit. A similar phenomenon explains the Plutino puzzle of the early evolution of the solar system.

Such information channel is inherently noisy and must adapt through evolution to cope with the potential errors. Can such optimization explain the origins of biological codes? - We examine a scenario in which evolution drives the emergence of a genetic code by selecting for a map that minimizes the impact of errors. The emergence of the code is actually a phase transition that is governed by the topology of noise. Similar phase transitions may suggest a mechanism for the formation of other error-prone biological codes, such as the transcription network.
