BCS-BEC crossover in a system of microcavity polaritons
BCS-BEC crossover in a system of microcavity polaritons
We investigate the thermodynamics and signatures of a polariton condensate over a range of densities, using a model of microcavity polaritons with internal structure. We determine a phase diagram for this system including fluctuation corrections to the mean-field theory. At low densities the condensation temperature, T_c, behaves like that for …
