The features of collective level shift and line broadening in a fabry-perot microcavity and near the conducting surface

Abstract

On the basis of consequent microscopic quantum approach we calculate collective level shifts and line broadening in the polyatomic ensemble located in the Fabry-Perot cavity or near the conducting surface. We show that the cavity or the surface can essentially modify dipole-dipole interaction and consequently spectral properties of studied impurity ensembles. This modification is explained by the peculiarities of the structure of modes of electromagnetic field in these cases.
