| Abstract: | For two coupled identical quantum dots in a two-mode cavity, we determine the conditions of two-photon and single-photon resonance. It is shown that the exciton-phonon interaction reduces the Rabi frequencies of each model and the Förster interaction between double quantum dots even at absolute zero temperature. The exciton-phonon interaction also makes a contribution to the static exciton-exciton dipole interaction energy. Furthermore, the additional interactions can modify the conditions of photon resonance significantly. A more realistic case of two nonidentical quantum dots is also considered. The influence of parameter misfits on the quantum system is discussed.Received: 8 July 2004, Published online: 3 November 2004PACS: 73.21.La Quantum dots - 71.35.-y Excitons and related phenomena - 42.50.Pq Cavity quantum electrodynamics; micromasers |
