Abstract: We introduce a modified Jaynes-Cummings model with single-photon cavity radiationfield but with the atomic system instead of exchanging a single photon as in the Jaynes-Cummingsmodel, it exchanges instead a squeezed photon with squeezing parameter r. This allows us tointerpolate between the Rabi model (r = 8) and the Jaynes-Cummings model (r = 0) by varying r.The model exhibits a quantum phase transition. Accordingly, the quantum phase transitionrealized in the Rabi model, giving rise to superradiance, also occurs in the Jaynes-Cummingsmodel.
