Static Casimir Condensate of Conformal Scalar Field in Friedmann Universe
arXiv:1805.09516 · doi:10.1142/S0217732318501626
Abstract
The quantum Casimir condensate of a conformal massive scalar field in a compact Friedmann universe is considered in the static approximation. The Abel-Plana formula is used for renormalization of divergent series in the condensate calculation. A differential relation between the static Casimir energy density and static Casimir condensate is derived.
