Superfluidity and collective properties of excitonic polaritons in gapped graphene in a microcavity
arXiv:1205.4784 · doi:10.1103/PhysRevB.86.235404
Abstract
We predict the formation and superfluidity of polaritons in an optical microcavity formed by excitons in gapped graphene embedded there and microcavity photons. The Rabi splitting related to the creation of an exciton in a graphene layer in the presence of the band gap is obtained. The analysis of collective excitations as well as the sound velocity is presented. We show that the superfluid density and temperature of the Kosterlitz-Thouless phase transition are decreasing functions of the energy gap.
