Abstract

By considering a microscopical model, we derive an evolution equation for single-mode polariton condensate taking into account the fluctuations of the order parameter. We use it to derive an analytical expression for the second order correlation function and the share of coherent occupation of the condensate in presence of pumping-leakage balance.
