Abstract:
We estimate the condensation temperature for microcavity polaritons, allowing for their internal
structure. We consider polaritons formed from localized excitons in a planar microcavity, using a
generalized Dicke model. At low densities, we find a condensation temperature Tc / , as expected for a
gas of structureless polaritons. However, as Tc becomes of the order of the Rabi splitting, the structure
of the polaritons becomes relevant, and the condensation temperature is that of a BCS-like mean-field
theory.We also calculate the excitation spectrum, which is related to observable quantities such as the
luminescence and absorption spectra.
