On Stefan-Boltzmann law and the Casimir effect at finite temperature in the Schwarzschild spacetime
arXiv:2004.12701 · doi:10.1142/S0217751X20500669
Abstract
This paper deals with quantum field theory in curved space-time using the Thermo Field Dynamics. The scalar field is coupled to the Schwarzschild space time and then thermalised. The Stefan-Boltzmann law is established at finite temperature and the entropy of the field is calculated. Then the Casimir energy and pressure are obtained at zero and finite temperature.
