Thermodynamic properties of a relativistic Bose gas under rigid rotation

Abstract: The investigation of the impact of rotation on fermionic and bosonic systems has recently become a significant area of research in finite temperature field theory. In this work, we focus on a system of relativistic Bose gas subjected to a rigid rotation and analyze its thermodynamic properties. First, we introduce the rigid rotation metric and derive the solutions of the Klein-Gordon equation in cylindrical coordinates. We then calculate the propagator of a rotating bosonic system by making use of the generalized Fock-Schwinger proper-time method. Using the imaginary time formalism at finite temperature, we compute the thermodynamic potential of the system up to the first order of perturbative expansion. Additionally, we determine the nonperturbative ring contribution to the thermodynamic potential. Utilizing this potential, we calculate some thermodynamic quantities, such as pressure, energy density, entropy density, and angular momentum density. The obtained results show that the moment of inertia becomes negative in certain regimes of the parameter space. Our results are similar to the recent findings for the moment of inertia of a rotating gluonic plasma, where a supervortical temperature is introduced.
