Cavity confinement of quantum materials can induce a strong coupling between the electronic system and the quantum electromagnetic field, potentially leading to novel quantum phenomena of light and matter. The authors study here how the ultrastrong light-matter coupling can affect the Kondo effect. Nonperturbative analyses show that the ultrastrong coupling can enhance the Kondo temperature and give rise to several notable phenomena, including universal scalings of the cavity-modified Kondo effect, the photon occupation number, and the entanglement entropy between the cavity and electrons.
