Abstract
We present a general, semi-microscopic, self-consistent treatment of spontaneous emission for a two-level atom in a dielectric microcavity with arbitrary shape and size. Lossless and absorbing media are considered. The approach is based on linear-response theory and the coupled dipole method. We compute decay rates and classical frequency shifts. By considering an atom in a spherical cavity, we identify the Purcell effect, the local-field factor and the near-field dipole-dipole interaction, and we show how the real-cavity local-field factor is enhanced by radiation reaction.Citation
