Fluctuation theorems in driven open quantum systems — Peter Talkner, •Michele Campisi, and Peter Hänggi — Institute of Physics, University of Augsburg, D-86135 Augsburg, Germany

The statistics of the internal energy, the exchanged heat and the work of a quantum system that weakly couples to its environment is determined in terms of the energy changes of the system and the environment due to the action of a classical, external force on the system [1,2]. If the system and environment initially are in a canonical equilibrium, the work performed on the system is shown to satisfy the Tasaki-Crooks theorem [3] and the Jarzynski equality [4].
