Quantum Phase Transition in the Dicke Model
Published 16 Jul 2025 in quant-ph | (2507.12332v1)
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.
