详细
Dynamics of exciton-polariton Bose‒Einstein condensate in an optical microcavity is considered. A novel version of stochastic Gross‒Pitaevsky equation for description of condensate evolution under non-Markovian interaction with environment is proposed. Using the proposed version, analysis of condensate dynamics for various temperatures is carried out. The phase transition from a homogeneous to fragmented condensate state near temperature of 15 K is found. This phase transition is accompanied by drop of condensate density and decrease of correlation length. It is found that correlation length oscillates with time for the temperature of 10 K. The results obtained indicate the necessity to take into account non-Markovianity of condensate interaction with the excitonic reservoir.
