Photon propagator in de Sitter space in the general covariant gauge
Abstract We consider a free photon field in D-dimensional de Sitter space, and construct its propagator in the general covariant gauge. Canonical quantization is employed to define the system starting from the classical theory. This guarantees that the propagator satisfies both the equation of motio...
