Quantum Phase Transition in a Modified Jaynes-Cummings Model (2405.15876v1)
Published 24 May 2024 in quant-ph
Abstract: We introduce a modified Jaynes-Cummings model with single-photon cavity radiation field but with the atomic system instead of exchanging a single photon as in the Jaynes-Cummings model, it exchanges instead a squeezed photon with squeezing parameter r. This allows us to interpolate between the Rabi model, r = infinity, and the Jaynes-Cummings model, r = 0, by varying r. The model exhibits a quantum phase transition. Accordingly, the quantum phase transition realized in the Rabi model, giving rise to superradiance, also occurs in the Jaynes-Cummings model
