Quantum Phase Transitions in Many-Dipole Light-Matter Systems
Daniele Lamberto, Omar Di Stefano, Stephen Hughes +2
A potential phase transition between a normal ground state and a photon-condensed ground state in many-dipole light-matter systems is a topic of considerable controversy, exasperat…

Photon condensation, Van Vleck paramagnetism, and chiral cavities
Alberto Mercurio, Gian Marcello Andolina, Francesco M. D. Pellegrino +6
We introduce a gauge-invariant model of planar, square molecules coupled to a quantized spatially-varying cavity electromagnetic vector potential A(r). Specifically, we choose a te…
