Casimir effect for the robin surfaces in static robertson-walker space-time

摘要

We investigate the energy-momentum tensor for a massless conformally coupled scalar field in the region between two curved surfaces in k = -1 static Robertson-Walker space-time. We assume that the scalar field satisfies the Robin boundary condition on the surfaces. RobertsonWalker spacetime space is conformally related to Rindler space; as a result we can obtain vacuum expectation values of the energy-momentum tensor for a conformally invariant field in Robertson-Walker space-time space from the corresponding Rindler counterpart by the conformal transformation.
