Driven chaotic mesoscopic systems, dissipation and decoherence
Doron Cohen
Driven chaotic systems are of interest in mesoscopic physics, as well as in nuclear, atomic and molecular physics. Such systems [coordinates ]$ tend to absorb energy. This i…
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…
Overview: Energy Absorption by Driven Mesoscopic Systems
Doron Cohen
There are three regimes in the theory of energy absorption: The adiabatic regime, the linear-response (Kubo) regime, and the non-perturbative regime. The mesoscopic Drude formula f…
Overview: Brownian Motion and Dephasing due to Dynamical Disorder
Doron Cohen
The motion of a particle under the influence of a dynamical disorder is described by the DLD model. One motivation is to understand the motion of an electron inside a metal; Anothe…
Non Perturbative Destruction of Localization in the Quantum Kicked Particle Problem
Doron Cohen
The angle coordinate of the Quantum Kicked Rotator problem is treated as if it were an extended coordinate. A new mechanism for destruction of coherence by noise is analyzed using…
Chaos, Dissipation and Quantal Brownian Motion
Doron Cohen
Energy absorption by driven chaotic systems, the theory of energy spreading and quantal Brownian motion are considered. In particular we discuss the theory of a classical particle…
