Quantum Phase Transition in the Dicke Model
arXiv:2507.12332 · doi:10.54503/18291171-2025.18.2-18
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.
