THE INFLUENCE OF LOCAL-FIELD CORRECTION ON THE STRONG-COUPLING REGIME

Abstract

Using the real-cavity model, we consider the influence of the local-field correction on the strong atom-field coupling regime. The atom is positioned at the center of a Bragg-distributed spherical resonator that can now be fabricated in laboratories. The Rabi oscillation frequency and the condition indicating the occurrence of the strong-coupling regime are studied. Effects of the local-field correction may eventually destroy the strong-coupling regime. It is also especially pronounced at high-material densities due to direct energy transfer from the atom to medium. At lower material density and/or material absorption, variation of material density does not to affect much the strong-coupling regime, except for a small shift in the resonance frequency.
