Dephasing processes in quantum dot microcavity systems: a microscopic description — •Sandra Ritter, Christopher Gies, Jan Seebeck, Jan Wiersig, and Frank Jahnke — Institut für Theoretische Physik, Universität Bremen

Due to various applications the system of quantum dots placed in three-dimentional optical resonators receives great attention. Starting from a fully quantum mechanical description of the carrier-photon interaction for quantum dots in microcavities, we study the influence of carrier scattering and dephasing on the emission properties. A consistent inclusion of scattering processes in various carrier and photon correlation functions is realized by coupling to acoustic phonons. The interplay of scattering and dephasing is of particular importance in the good cavity regime, where the cavity loss rate is smaller than the spontaneous emission rate of the quantum dots into the cavity.
