The first realization of a polariton condensate was recently achieved in a CdTe microcavity [ Kasprzak et al. Nature (London) 443 409 (2006)]. We compare the experimental phase boundaries, for various detunings and cryostat temperatures, with those found theoretically from a model which accounts for features of microcavity polaritons such as reduced dimensionality, internal composite structure, disorder in the quantum wells, polariton-polariton interactions, and finite lifetime.
