Bose–Einstein condensation of polaritons
Polariton condensation / From Wikipedia, the free encyclopedia
Bose–Einstein condensation of polaritons is a growing field in semiconductor optics research, which exhibits spontaneous coherence similar to a laser, but through a different mechanism. A continuous transition from polariton condensation to lasing can be made similar to that of the crossover from a Bose–Einstein condensate to a BCS state in the context of Fermi gases.[1][2] Polariton condensation is sometimes called “lasing without inversion”.[3][4]
