Green's Function expansion of scalar and vector fields in the presence of a medium
arXiv:1010.3423 · doi:10.1103/PhysRevA.84.062122
Abstract
Based on a canonical approach and functional-integration techniques, a series expansion of Green's function of a scalar field, in the presence of a medium, is obtained. A series expansion for Lifshitz-energy, in finite-temperature, in terms of the susceptibility of the medium is derived and the whole formalism is generalized to the case of electromagnetic field in the presence of some dielectrics. A covariant formulation of the problem is presented.
