Quantization of electrodynamics in curved spacetime in the Lorentz gauge and with arbitrary gauge parameter makes it necessary to study Green functions of non-minimal operators with variable coefficients. Starting from the integral representation of photon Green functions, we link them to the evaluation of integrals involving Γ-functions. Eventually, the full asymptotic expansion of the Feynman photon Green function at small values of the world function, as well as its explicit dependence on… 

Energy-momentum tensor for a Casimir apparatus in a weak gravitational field

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. We use Fermi

A Derivation Of The Scalar Propagator In A Planar Model In Curved Space

Given that the free massive scalar propagator in 2+1 dimensional Euclidean space is D(x−y) = 14πρe−mρ with ρ2 = (x−y)2 we present the counterpart of D(x−y) in curved space with a suitably modified

Novel features of the energy–momentum tensor of a Casimir apparatus in a weak gravitational field

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

The Gribov phenomenon in flat and curved spaces

The quantization of Yang–Mills theories relies on the gauge-fixing procedure. However, in the non-Abelian case this procedure leads to the well-known Gribov ambiguity. In order to solve the ambiguity

Gravitational Waves about Curved Backgrounds: a Consistency Analysis in de Sitter Spacetime

Gravitational waves are considered as metric perturbations about a curved background metric, rather than the flat Minkowski metric since several situations of physical interest can be discussed by

Gauge field theories and propagators in curved space-time

In this paper DeWitt’s formalism for field theories is presented; it provides a framework in which the quantization of fields possessing infinite dimensional invariance groups may be carried out in a

Divergent part of the stress-energy tensor for Maxwell’s theory in curved space-time: a systematic derivation

In this paper the Feynman Green function for Maxwell’s theory in curved space-time is studied by using the Fock–Schwinger–DeWitt asymptotic expansion; the point-splitting method is then applied,

Electromagnetic and Gravitational Waves on a de Sitter background

One of the longstanding problems of modern gravitational physics is the detection of gravitational waves, for which the standard theoretical analysis relies upon the split of the space-time metric g

Description of charging/discharging processes of the LISA sensors

The next generation of gravitational experiments in space is likely to use completely isolated proof-masses. For example, LISA uses proof-masses as mirrors in interferometers for gravitational wave

On the Occurrence of Mass in Field Theory

This paper proves that it is possible to build a Lagrangian for quantum electrodynamics which makes it explicit that the photon mass is eventually set to zero in the physical part on observational

It is shown that, although for scalars there is a direct connection, this is not true for photons, and the relevance of these results to the approximation of renormalized stress tensors in static Einstein space-times is discussed.

Casimir energy in the axial gauge

The zero-point energy of a conducting spherical shell is studied by imposing the axial gauge via path-integral methods, with boundary conditions on the electromagnetic potential and ghost fields. The

When graviton loops are taken into account, the background metric obtained as a solution to the one-loop corrected Einstein equations turns out to be gauge-fixing dependent. Therefore it is of no
