Abstract

The spatio-temporal dynamics of quantum well excitons interacting with photons and phonons in a disordered landscape are examined. The theory is based on a microscopical description for phonons, photons and disorder in a spatially inhomogeneous system. For resonant excitation of 1s excitons, the Heisenberg equation of motion for polarization, exciton density, and their assisted quantities are expanded in excitonic wavefunctions. Considering low excitation phenomena, a closed set of equations is determined, where the disorder is treated by a configuration average. The resulting hierarchy of disorder correlation functions is truncated by neglecting terms higher than second order using a weak memory approximation.
