In this work, we study the thermodynamics of a hybrid system based on the Da Providencia–Schütte Hamiltonian. The model consists of bosons, i.e., photons in a cavity, interacting with anensemble of spins through a pseudo-Hermitian Hamiltonian. We compute the exact partition functionof the system, and from it, we derive the statistical properties of the system. Finally, we evaluate thework that can be extracted from the system by performing an Otto cycle and discuss the advantagesof the proposed pseudo-Hermitian interaction.
