Abstract:Exciton-polariton condensate in semiconductor microcavities constitute a novel kind of nonequilibrium superfluid. In a recent experiment [P. Stepanov, et. al., Nat. Commun. 10, 1038(2019], the dispersion relation of collective excitations in a polariton condensate under the resonant pumping has been investigated with the emphasis on the role of reservoir of long-lived excitons in determining the superfluidity. Inspired by such an experimental advance, we study the superfluidity of a exciton-polaritonn condensa… Show more
