Collective fluorescence and decoherence of a few nearly identical quantum dots
arXiv:cond-mat/0606647 · doi:10.1103/PhysRevB.75.035328
Abstract
We study the collective interaction of excitons in closely spaced artificial molecules and arrays of nearly identical quantum dots with the electromagnetic modes. We discuss how collective fluorescence builds up in the presence of a small mismatch of the transition energy. We show that a superradiant state of a single exciton in a molecule of two dots with realistic energy mismatch undergoes a two-rate decay. We analyze also the stability of subdecoherent states for non-identical systems.
