Irreversibility and entropy production in open quantum systems — •Nico Krause and Heinz-Peter Breuer — Physikalisches Institut, Albert-Ludwigs-Universität Freiburg, Germany

On the basis of various random matrix models we investigate the degree of irreversibility of the dynamics of open quantum systems. Starting from the exact expression for the irreversible entropy production in terms of relative entropy, our central goal is the derivation of suitable approximate expressions which only refer to open system degrees of freedom. The result allows an efficient determination of the entropy production of quantum thermodynamic processes using information theoretical concepts.
