Rabi oscillations in a quantum dot-cavity system coupled to a nonzero temperature phonon bath

Abstract

We study a quantum dot strongly coupled to a single high-finesse optical microcavity mode. We use a rotating wave approximation (RWA) method, commonly used in ion–laser interactions, together with the Lamb–Dicke approximation to obtain an analytic solution of this problem. The decay of Rabi oscillations because of the electron–phonon coupling is studied at arbitrary temperature and analytical expressions for the collapse and revival times are presented. Analyses without the RWA are presented as means of investigating the energy spectrum.
