Abstract:
A trapped polariton condensate with continuous pumping and decay is analyzed using a generalized Gross?
Pitaevskii model. Whereas an equilibrium condensate is characterized by a macroscopic occupation of a
ground state, here the steady states take more general forms. Some are characterized by a large population in
an excited state; others by large populations in several states, which may overlap spatially. In the latter case, the
highly populated states synchronize to a common frequency above a critical density. At intermediate densities,
they can drive condensation in other trap modes by parametric scattering. Estimates for the critical density of
the synchronization transition are consistent with experiments
