Dynamical chaos versus quantum interference
Valentin V. Sokolov, Giuliano Benenti, Giulio Casati
We discuss the dephasing induced by the internal classical chaotic motion in the absence of any external environment. To this end a new extension of fidelity for mixed states is in…
Magnetically Induced Thermal Rectification
Giulio Casati, Carlos Mejia-Monasterio, Tomaz Prosen
We consider far from equilibrium heat transport in chaotic billiard chains with non-interacting charged particles in the presence of non-uniform transverse magnetic field. If half…
Classical and Quantum Chaos and Control of Heat Flow
Giulio Casati, Carlos Mejia-Monasterio
We discuss the problem of heat conduction in classical and quantum low dimensional systems from a microscopic point of view. At the classical level we provide convincing numerical…
Many-body quantum ratchet in a Bose-Einstein condensate
Dario Poletti, Giuliano Benenti, Giulio Casati +1
We study the dynamics of a dilute Bose-Einstein condensate confined in a toroidal trap and exposed to a pair of periodically flashed optical lattices. We first prove that in the no…
Conservative chaotic map as a model of quantum many-body environment
Davide Rossini, Giuliano Benenti, Giulio Casati
We study the dynamics of the entanglement between two qubits coupled to a common chaotic environment, described by the quantum kicked rotator model. We show that the kicked rotator…
Chaotic ratchet dynamics with cold atoms in a pair of pulsed optical lattices
Gabriel G. Carlo, Giuliano Benenti, Giulio Casati +4
We present a very simple model for realizing directed transport with cold atoms in a pair of periodically flashed optical lattices. The origin of this ratchet effect is explained a…
