Atom-only theories for U(1) symmetric cavity-QED models
Roberta Palacino, Jonathan Keeling
We consider a generalized Dicke model with U(1) symmetry, which can undergo a transition to a superradiant state that spontaneously breaks this symmetry. By exploiting the differen…

Time-dependent resonance interaction energy between two entangled atoms under non-equilibrium conditions
Giuseppe Fiscelli, Roberta Palacino, Roberto Passante +3
We consider the time-dependent resonance interaction energy between two identical atoms, one in the ground state and the other in an excited state, and interacting with the vacuum…
