Superradiant Phase is a Finite Size Effect in Two-photon Processes
Fabrizio Ramírez, David Villaseñor, Nahum Vázquez +1
Two-photon light-matter interactions exhibit distinctive features such as spectral collapse. The two-photon Dicke model has been reported to exhibit a superradiant phase which coul…
