Abstract
The influence of the gravity acceleration on the regularized energy–momentum tensor of the quantized electromagnetic field between two plane parallel conducting plates is derived. A perturbative expansion, to first order in the constant acceleration parameter, of the Green functions involved and of the energy–momentum tensor is derived by means of the covariant geodesic point splitting procedure. The energy–momentum tensor is covariantly conserved and satisfies the expected relation between gauge-breaking and ghost parts.File | Dimensione | Formato | |
