Mott polaritons in cavity-coupled quantum materials

Mott polaritons in cavity-coupled quantum materials

We show that strong electron–electron interactions in quantum materials can give rise to electronic transitions that couple strongly to cavity fields, and collective enhancement of these interactions can result in ultrastrong effective coupling strengths. As a paradigmatic example we consider a Ferm...
