Cavity superconductor Higgs-polaritons

Motivated by the dramatic success of cavity exciton-polariton physics we consider the formation of a polariton from cavity photons and the amplitude mode of a disordered superconductor. Enabled by the recently predicted and observed supercurrent-induced coupling between these excitations we find that signficant hybridization between cavity photons and Higgs excitations in a quasi-2D superconductor can occur. We analyze the character and damping of the hybrid modes.
