Thermodynamics of quantum Brownian motion with internal degrees of freedom — •Christian Hörhammer and Helmut Büttner — Theoretische Physik I, Universität Bayreuth, 95440 Bayreuth

We examine the role of entanglement in the low temperature/ strong-coupling quantum regime and the applicability of thermodynamic relations such as the Clausius inequality. A model of two coupled Brownian oscillators based on the Caldeira-Leggett model is formulated and the influence of the additional internal coupling parameter on heat and entropy changes is described. The results are compared to the case of quantum motion of a single Brownian particle.
