Quantum Thermodynamics of an atom-cavity system with Jaynes-Cummings interaction

In this paper we give an introduction to the ideas of quantum thermodynamics, using only basic concepts from quantum and statistical mechanics. Then, we discuss the framework of non-equilibrium processes in quantum systems and introduce how to calculate quantities such as work and irreversible entropy in these processes. We then apply these results to the problem of atom-cavity system while their interaction describe by Jaynes-Cummings model with both weak and strong atom-cavity coupling. Here, we introduce the concept of quantum thermodynamics of close quantum system and so by considering a good cavity, coupling of cavity modes with its reservoir has been omitted.
