Back-reaction of Quantum fields in an Einstein Universe [PDF]
Phys.Rev. D65 (2002) 044028, 2001 We study the back-reaction effects of the finite-temperature scalar field and the photon field in the background of an Einstein universe. In each case we find a relation between the temperature of the universe and its radius. These relations exhibit a minimum radius below which no self-consistent solution for the Einstein field equation can be found. A
