Superconductor-polariton nondissipative drag in optical microcavity

Year: 2023
Type: article
Abstract: We consider nondissipative drag between Bose-condensed exciton polaritons in optical microcavity and embedded superconductors. This effect consists of induction of a nondissipative electric current in the superconductor by motion of polariton Bose condensate due to electron-polariton interaction, or vice versa. Using many-body theory, we calculate the drag density, characterizing magnitude of this effect, with taking into account dynamical screening of the interaction. Hoping to diminish the interaction screening and microcavity photon absorption, we consider atomically thin superconductors (both conventional $s$-wave and copper-oxide $d$-wave) of planar and nanoribbon shapes. Our estimates show that in realistic conditions the drag effect could be rather weak but observable in accurate experiments in the case of dipolar interlayer excitons in transition metal dichalcogenide bilayers. Use of spatially direct excitons, semiconductor quantum wells as the host for excitons, or thin films of bulk metallic superconductors considerably lowers the drag density.
