摘要
We report results on the theoretical study of the ultrafast relaxation of polaritons in semiconductor microcavities. The photoluminescence decay dynamics is found to be controlled by the initial density of excitons. In the high density regime, the parametric conversion of excitons dominates the relaxation with memory (Non-Markov) effects producing a non-monotonous decay of the emission signal. This behavior agrees with recent experimental observations.
