Singular behavior of the photon density of states and the self-energy function of an electron in photonic crystal

Abstract

© Published under licence by IOP Publishing Ltd. We show that Van Hove singularities in the behavior of the photon density of states in a photonic crystal results in a singular behavior of the self-energy functions of atomic states that describe the interaction of the atom with vacuum. This is shown to have a significant effect on processes of quantum interference from atoms in the PC medium.
