Extended Bose-Hubbard model with pair tunneling: spontaneous symmetry breaking, effective ground state and fragmentation
Qizhong Zhu, Qi Zhang, Biao Wu
The extended Bose-Hubbard model for a double-well potential with pair tunneling is studied through both exact diagonalization and mean field theory (MFT). When pair tunneling is st…

Synthetic Spin-Orbit Coupling in Two-level Cold Atoms
Qi Zhang, Jiangbin Gong, C. H. Oh
Synthetic spin-orbit coupling (SOC) in controlled quantum systems such as cold atoms or trapped ions has been of great interest. Here we show, both theoretically and computationall…
