摘要: We consider the mechanical coupling between a two-dimensional Bose–Einstein condensate and graphene sheet via vacuum fluctuations of electromagnetic field which are at origin so-called Casimir–Polder potential. By deriving self-consistent set equations governing dynamics flexural (out-of-plane) modes graphene, we can show formation new type purely acoustic quasi-particle excitation, quasi-polariton resulting from coherent superposition quanta Bogoliubov modes.
