Model Studies on the Quantum Jarzynski Relation — •Jens Teifel and Günter Mahler — Universität Stuttgart, Institut für Theoretische Physik I, 70550 Stuttgart, Pfaffenwaldring 57/IV

We are particularly interested in the quantum Jarzynski relation, which has been shown to hold for closed quantum systems by S. Mukamel. We discuss different models of bipartite quantum systems, such as microcanonical coupling and canonical coupling. By generalizing the proof of Mukamel we show that the Jarzynski relation holds for microcanonical coupling as well as for open quantum systems at high initial temperatures. Furthermore we want to discuss a possible alteration of the Jarzynski relation in order to avoid the ambiguous definition of work in quantum systems.
