Steering Bose-Einstein condensates despite time symmetry
Dario Poletti, Giuliano Benenti, Giulio Casati +2
A Bose-Einstein condensate in an oscillating spatially asymmetric potential is shown to exhibit a directed current for unbiased initial conditions despite time symmetry. This pheno…
Thermoelectric transport in billiard systems
Giulio Casati, Carlos Mejia-Monasterio
We discuss the thermoelectric (TE) transport in billiard systems of interacting particles, coupled to stochastic particle reservoirs. Recently in [1], analytical exact expressions…
How complex is the quantum motion?
Giuliano Benenti, Giulio Casati
In classical mechanics the complexity of a dynamical system is characterized by the rate of local exponential instability which effaces the memory of initial conditions and leads t…
Complexity of Quantum States and Reversibility of Quantum Motion
Valentin V. Sokolov, Oleg V. Zhirov, Giuliano Benenti +1
We present a quantitative analysis of the reversibility properties of classically chaotic quantum motion. We analyze the connection between reversibility and the rate at which a qu…
Negative differential conductivity in far-from-equilibrium quantum spin chains
Giuliano Benenti, Giulio Casati, Tomaz Prosen +1
We show that, when a finite anisotropic Heisenberg spin-1/2 chain in the gapped regime is driven far from equilibrium, oppositely polarized ferromagnetic domains build up at the ed…
Increasing thermoelectric efficiency towards the Carnot limit
Giulio Casati, Carlos Mejia-Monasterio, Tomaz Prosen
We study the problem of thermoelectricity and propose a simple microscopic mechanism for the increase of thermoelectric efficiency. We consider the cross transport of particles and…
Entanglement-induced Decoherence and Energy Eigenstates
Wen-ge Wang, Jiangbin Gong, G. Casati +1
Using recent results in the field of quantum chaos we derive explicit expressions for the time scale of decoherence induced by the system-environment entanglement. For a generic sy…
