Abstract

By considering driven diffusive dynamics of exciton polaritons in an optical microcavity with an embedded molybdenum disulfide (${\mathrm{MoS}}_2$) 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 $P>600\mathrm{mW}$ and a trapping potential strength of $k>50\mathrm{eV}/{\mathrm{cm}}^2$. 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.
