We investigate theoretically the quantum oscillator-like states recently observed experimentally in polariton condensates. We consider a complex Gross–Pitaevskii-type model that includes the effects of self-interactions, and creation and decay of exciton-polaritons. We develop a perturbation theory for approximate solutions to this non-equilibrium condensate model and compare the results with numerically calculated solutions for both repulsive and attractive polariton–polariton interactions… Expand

TLDR
This work demonstrates a non-equilibrium BEC of exciton-polaritons in a polymer-filled microcavity at room temperature and observes thermalization of polaritons and clear evidence of condensation at zero in-plane momentum. Expand
