Stochastic classical field model for polariton condensates
We use the truncated Wigner approximation to derive stochastic classical field equations for the description of polariton condensates. Our equations are shown to reduce to the Boltzmann equation in the limit of low polariton density. Monte Carlo simulations are performed to analyze the momentum distribution and the first- and second-order coherences when the particle density is varied across the condensation threshold.
