Equilibration and thermalization in closed quantum systems — •Christian Gogolin, Arnau Riera, and Jens Eisert — Dahlem Center for Complex Quantum Systems, Freie Universitat Berlin, 14195 Berlin, Germany

Why and how do closed macroscopic systems equilibrate and thermalize? How can we justify the methods of thermodynamics and statistical mechanics from the microscopic theory of quantum mechanics? How can one prepare thermal states in quantum simulators? Which mechanisms lead to the emergence of classical, statistical behavior and decoherence? We show how methods from quantum information theory can help to attack such questions, which are fundamental on the one hand, but which have recently gained new relevance in the light of experiments with ultra cold atoms and ions in optical latices.
