{wiki=Bose–Einstein_condensation_of_polaritons}
Bose-Einstein condensation (BEC) of polaritons refers to the phenomenon where a dilute gas of polaritons, which are hybrid quasi-particles that arise from the coupling of photons with excitons (bound electron-hole pairs in a semiconductor), can occupy the same quantum state and exhibit collective behaviors at very low temperatures.
