Classical and quantum pumping in closed systems
Doron Cohen
Pumping of charge (Q) in a closed ring geometry is not quantized even in the strict adiabatic limit. The deviation form exact quantization can be related to the Thouless conductanc…
Non-perturbative response: chaos versus disorder
Doron Cohen, Tsampikos Kottos
Quantized chaotic systems are generically characterized by two energy scales: the mean level spacing , and the bandwidth . This implies that with respect to dri…
Stadium Billiard with Moving Walls
Doron Cohen, Diego A. Wisniacki
We study the evolution of the energy distribution for a stadium with moving walls. We consider one period driving cycle, which is characterized by an amplitude and wall velocit…
Persistent currents in Moebius strips
Kousuke Yakubo, Yshai Avishai, Doron Cohen
Relation between the geometry of a two-dimensional sample and its equilibrium physical properties is exemplified here for a system of non-interacting electrons on a Moebius strip.…
Quantum Chaos, Irreversibility, dissipation and dephasing
Doron Cohen
The main idea of "Quantum Chaos" studies is that Quantum Mechanics introduces two energy scales into the study of chaotic systems: One is obviously the mean level spacing $Δ\propto…
Quantum Irreversibility of Energy Spreading
Tsampikos Kottos, Doron Cohen
The analysis of dissipation and dephasing in driven mesoscopic devices requires a distinction between two notions of quantum irreversibility. One ("Loschmidt echo") is related to "…
