QED of excitons with nonlocal susceptibility in arbitrary-structured dielectrics
arXiv:0708.2952 · doi:10.1103/PhysRevB.78.085109
Abstract
We have constructed a complete quantum theory for an optical process of excitons with nonlocal susceptibility originating from their center-of-mass motion. This theory provides a practical calculation method for arbitrary-structured nano-to-macro scale dielectrics where excitons are weakly confined. We obtain good correspondences with underlying theories, semiclassical microscopic nonlocal theory, and QED theories for dispersive and absorptive materials with local susceptibility.
