Quantum Phase Transition in the Dicke Model

We consider a previously modified Jaynes-Cummings model with single-photon cavity radiation field and atomic system exchanging a squeezed photon and deduce a normal/superradiance quantum phase transition in the Dicke model of N atoms of arbitrary spin with independent co- and counter-rotating coupling terms.

Abstract

We consider a previously modified Jaynes-Cummings model with single-photon cavity radiation field and atomic system exchanging a squeezed photon and deduce a normal/superradiance quantum phase transition in the Dicke model of N atoms of arbitrary spin with independent co- and counter-rotating coupling terms.
