Cavity Higgs-Polaritons

The authors derive hybrid light-matter excitations formed from photons and the elusive Higgs mode of superconductors. A model of a thin-film superconductor placed in a planar microwave cavity is considered. By driving a supercurrent through the thin film a substantial mixing between Higgs modes and light can be achieved. Photon tunneling through the cavity allows for a direct observation of the hybridized states.

Cavity Quantum Eliashberg Enhancement of Superconductivity

Driving a conventional superconductor with an appropriately tuned classical electromagnetic field can lead to an enhancement of superconductivity via a redistribution of the quasiparticles into a more favorable nonequilibrium distribution—a …

Properties of superconductors coupled to photonic cavities

We study the phenomena which can arise when cavity photons are strongly coupled to superconductors.

Cavity superconductor-polaritons

Following the recent success of realizing exciton-polariton condensates in cavities, we examine the hybridization of cavity photons with the closest analog of excitons within a superconductor, states called Bardasis-Schrieffer (BS) modes. Though BS …
