Observation of quantum depletion in a non-equilibrium exciton–polariton condensate

Superfluidity, first discovered in liquid (4)He, is closely related to Bose–Einstein condensation (BEC) phenomenon. However, even at zero temperature, a fraction of the quantum liquid is excited out of the condensate into higher momentum states via interaction-induced fluctuations—the phenomenon of...
