In this study, deviations from ideal gas behavior of a relativistic gas of charged scalar bosons caused by current-current interaction induced by electromagnetic quantum fluctuations were computed using scalar quantum electrodynamics. Expressions for those quantities in ultra-relativistic and nonrelativistic limits were obtained, and numerical results for the relativistic case were presented. (C) 2021 The Author(s).

We compute deviations from ideal gas behavior of the pressure, density, and Bose-Einstein condensation temperature of a relativistic gas of charged scalar bosons caused by the current-current interaction induced by electromagnetic quantum fluctuations treated via scalar quantum electrodynamics. We obtain expressions for those quantities in the ultra-relativistic and nonrelativistic limits, and present numerical results for the relativistic case. (C) 2021 The Author(s).
