Toward room-temperature superfluidity of exciton polaritons in an optical microcavity with an embedded MoS2 monolayer

By considering driven diffusive dynamics of exciton polaritons in an optical microcavity with an embedded molybdenum disulfide (MoS2) monolayer, we determine an experimentally relevant range of parameters at which room-temperature superfluidity can be observed. It is shown that the superfluid transitions occur in a trapped polariton gas at a laser pumping power of P > 600 mW and a trapping potential strength of k > 50 eV/cm(2). We also propose a simple analytic model that provides a useful estimate for the polariton gas density, which enables one to determine the conditions for the observation of room-temperature polariton superfluidity.
