Generalized Aubry-Andre-Harper Models in Optical Superlattices
Yi Li, Jia-Hui Zhang, Feng Mei +3
Ultracold atoms trapped in optical superlattices provide a simple platform for realizing the seminal Aubry-André-Harper (AAH) model. However, the periodic modulations on the neares…

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…

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…
