Analytical ground state for the Jaynes-Cummings model with the ultrastrong coupling
Yuanwei Zhang, Gang Chen, Lixian Yu +3
We present a generalized variational method to analytically obtain the ground-state properties of the unsolvable Jaynes-Cummings model with the ultrastrong coupling. An explicit ex…

Quantum resonant effect of the strongly-driven spin-boson model
Qifeng Liang, Lixian Yu, Gang Chen +1
In this paper we discuss both analytically and numerically the rich quantum dynamics of the spin-boson model driven by a time-independent field of photon. Interestingly, we predict…

Light-shift-induced quantum phase transitions of a Bose-Einstein condensate in the optical cavities
Ni Liu, Jinling Lian, Jie Ma +4
In this paper we reveal the rich ground-state properties induced by the strong nonlinear atom-photon interaction, which has been found in the recent experiment about a Bose-Einstei…
