Nonequilibrium entropy production for open quantum systems — •Sebastian Deffner and Eric Lutz — Department of Physics, University of Augsburg, D-86135 Augsburg, Germany

We consider a driven quantum system weakly coupled to a thermal environment. We provide a microscopic expression for the irreversible entropy production for general far from equilibrium processes and show that it fulfills an integral fluctuation theorem. Our derivation is solely based on thermodynamic arguments and does not rely on master equations or quantum trajectories.
