Studies on a Quantum Work-Fluctuation Theorem — •Jens Teifel and Günter Mahler — Universität Stuttgart, 70550 Stuttgart, Pfaffenwaldring 57/IV

If an external force acts on a thermodynamic system on a finite time scale, it may be driven out of equilibrium. The Jarzynski relation, a classical fluctuation theorem, connects the work performed on the system and the difference of the free energy of the initial and final state, respectively. A quantum analogue has been established by S. Mukamel [Phys. Rev. Lett. 90, 170604 (2003)]. Here, we study different models of bipartite systems for which we prove that the Jarzynski relation holds.
