Geometric phase in the Kitaev honeycomb model and scaling behavior at critical points
Jinling Lian, J. -Q. Liang, Gang Chen
In this paper a geometric phase of the Kitaev honeycomb model is derived and proposed to characterize the topological quantum phase transition. The simultaneous rotation of two spi…
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…
BCS-BEC crossover in spin-orbit coupled two-dimensional Fermi gases
Gang Chen, Ming Gong, Chuanwei Zhang
The recent experimental realization of spin-orbit coupling for ultra-cold atoms has generated much interest in the physics of spin-orbit coupled degenerate Fermi gases. Although re…
