| 摘 要： | Herein, we propose an experimentally feasible scheme to show the quantum phase transition of the Jaynes-Cummings(JC) model by modulating the transition frequency of a two-level system in a quantum Rabi model with strong coupling. By tuning the modulation frequency and amplitude, the ratio of the effective coupling strength of the rotating terms to the effective cavity(atomic transition) frequency can enter the deep-strong coupling regime, while the counter-rotating terms can be neglected. Thus, ...
