Theory of electron dynamics in light emitting quantum dot devices

Quantum dot based light emitters can be used as laser and single photon devices[1]. In particular, we focus on the theory of InAs/GaAs quantum dots (QDs) embedded in a two dimensional wetting layer (WL). For simulating real devices, the interactions between electrons and holes confined in the QDs and the wetting layer are important. Therefore, we include Coulomb interaction as well as electron-phonon coupling, considering multi-phonon processes based on an effective multiphonon Hamilton operator. Within this theoretical approach, the investigation in temporal domain is carried out for two limits
