Abstract

Superradiant phase transitions, predicted to occur in the ultra-strong light-matter coupling regime, may offer a route to robust quantum coherence but have not yet been observed at thermal equilibrium. Here, such a transition is predicted in ErFeO3 at about 4 K, revealing unique ground state properties.
