On the characterization of generalized quantum thermodynamic machines — •Georg Reuther, Markus Henrich, and Günter Mahler — Institut für Theoretische Physik 1, Universität Stuttgart, 70569 Stuttgart

Quantum thermodynamic machines have attracted more and more attention in the past years. It is possible to show that a spin chain with a nearest neighbor Heisenberg interaction which is exposed to a global temperature gradient provided by two heat baths behaves like a heat pump or heat engine if parts of the chain are modulated periodically [1]. We characterize the behavior of different spin chain and spin network configurations with regard to efficiency and other thermodynamic properties.
