# Cavity Higgs-Polaritons

## TL;DR

This paper explores the formation of Higgs-polaritons, hybrid light-matter states arising from coupling cavity photons with Higgs modes in disordered superconductors, opening new avenues for controlling superconductivity and photonic devices.

## Contribution

It introduces the concept of Higgs-polaritons formed via supercurrent-induced coupling in disordered superconductors, a novel hybridization mechanism not previously studied.

## Key findings

- Hybrid Higgs-polariton states can form in disordered quasi-2D superconductors.
- Supercurrent-induced linear coupling enables interaction between Higgs modes and cavity photons.
- Potential applications include manipulating superconducting states and developing new photonic circuit elements.

## Abstract

Motivated by the dramatic success of realizing cavity exciton-polariton condensation in experiment we consider the formation of polaritons from cavity photons and the amplitude or Higgs mode of a superconductor. Enabled by the recently predicted and observed supercurrent-induced linear coupling between these excitations and light, we find that hybridization between Higgs excitations in a disordered quasi-2D superconductor and resonant cavity photons can occur, forming Higgs-polariton states. This provides the potential for a new means to manipulate the superconducting state as well as potential for novel photonic cavity circuit elements.
