About
I’m a PhD student at the physics department at BGU university, under the guidance of Prof. Doron Cohen. I have completed my Master’s thesis under the supervision of Prof. Amiram Leviatan. For more details about my MSc work, see here. I’ve been a teaching assistant at the following courses: Statistical Mechanics, Quantum 3 and Solid state I.
Research
I’m interested in various statisical-mechanics models. Mostly related to the spreading and diffusion of particles in various environments.
My current project focuses on the interplay between coherent and stochastic transitions of a quantum particle coupled to finite-temperature bathes. A nice demonstration of this interplay is the non-monotonicity of the velocity, or current, as a function of the bias (force). A related phenomena concerns the increasing of the current as disorder is introduced to the system. For some highlights see here.
