Relaxation into equilibrium under pure Schrödinger dynamics

P. Borowski (), J. Gemmer and G. Mahler

The European Physical Journal B: Condensed Matter and Complex Systems, 2003, vol. 35, issue 2, 255-259

Abstract: We consider bipartite quantum systems that are described completely by a state vector $\vert{\Psi(t)}\rangle$ and the fully deterministic Schrödinger equation. Under weak constraints and without any artificially introduced decoherence or irreversibility, the smaller of the two subsystems shows thermodynamic behaviour like relaxation into an equilibrium, maximization of entropy and the emergence of the Boltzmann energy distribution. This generic behaviour results from entanglement. Copyright Springer-Verlag Berlin/Heidelberg 2003
