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

Abstract

By considering driven diffusive dynamics of exciton polaritons in an optical microcavity with an embedded molybdenum disulfide monolayer, we determine experimentally relevant range of parameters at which room-temperature superfuidity can be observed. It is shown that the superfluid transitions occurs in a trapped polariton gas at laser pumping power P>600 mW and and trapping potential strength k > 50 eV/cm2. 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 observation of room temperature polariton superfluidity.
