摘要
Thermodynamics is a phenomenological theory of heat and work. Here we analyze to what extent quantum thermodynamic relations are immune to the underlying mathematical formulation of quantum mechanics. As a main result, we show that the Jarzynski equality holds true for all non-hermitian quantum systems with real spectrum. This equality expresses the second law of thermodynamics for isothermal processes arbitrarily far from equilibrium. In the quasistatic limit however, the second law is reflected in the Carnot bound and it is fulfilled even if some eigenenergies are complex provided they appear in conjugate pairs. Furthermore, we propose a setup to test our predictions. The quantum system in question consists of strongly interacting excitons and photons in a semiconductor microcavity.
