Thermodynamics and quantum effects — •Stefanie Hilt¹ and Eric Lutz² — ¹Institut für Quantenphysik, Universität Ulm, Deutschland — ²Institut für Physik, Universität Augsburg, Deutschland

We consider a system coupled to a heat reservoir modelled by a harmonic chain and discuss the influence of quantum effects on the equilibrium properties of the system. Special emphasis is put on the low temperature regime where quantum fluctuations play an important role. In particular, we use the negativity to quantify the entanglement created between the system and the reservoir.
