Effects of noise in different approaches for the statistics of polariton condensates
The second-order correlation function of the polariton condensate is calculated within two different approaches. Both approaches qualitatively reproduce the deviations from the full coherence of the second-order correlation function that have been observed in the experiments. However, a quantitative difference in the magnitude of the predicted deviations is found. This difference originates in the modeling of the polariton dynamics in the two approaches.
