Electromagnetic quantum shifts in relativistic Bose-Einstein condensation

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).

Automated summary

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).
