Thesis Title- Occupation and Counting Statistics in Closed Mesoscopic Systems

A current can be induced in a closed device by changing control parameters. The amount Q of particles that are transported via a path of motion, is characterized by its expectation value, and by its variance. More generally one is interested in the full counting statistics.

We analyze Ocupation and counting statistics in specific examples: double path coherent oscillations; double path adiabatic transfer; quantum stirring and persistent currents.  

Stirring is the operation of inducing a DC circulating current by means of AC periodic driving. As a deterministic classical analog of quantum stirring we consider the prototype “piston pump” operating on a ring. This can be regarded as a generalized Fermi-Ulam model, incorporating a finite-height moving wall (piston), and non trivial topology (ring).
