Quantum diffusion and thermalization at resonant tunneling
arXiv:1405.4163 · doi:10.1103/PhysRevA.89.053610
Abstract
Nonequilibrium dynamics and effective thermalization are studied in a resonant tunneling scenario via multilevel Landau-Zener crossings. Our realistic many-body system, composed of two energy bands, naturally allows a separation of degrees of freedom. This gives access to an effective temperature and single- and two-body observables to characterize the delocalization of eigenstates and the nonequilibrium dynamics of our paradigmatic complex quantum system.
