Controlling directed atomic motion and second-order tunneling of a spin-orbit-coupled atom in optical lattices
Xiaobing Luo, Zhao-Yun Zeng, Yu Guo +5
We theoretically explore the tunneling dynamics for the tight-binding (TB) model of a single spin-orbit-coupled atom trapped in an optical lattice subjected to lattice shaking and…

Spin squeezing in a spin-orbit coupled Bose-Einstein condensate
Li Chen, Yunbo Zhang, Han Pu
We study the spin squeezing in a spin-1/2 Bose-Einstein condensates (BEC) with Raman induced spin-orbit coupling (SOC). Under the condition of two-photon resonance and weak Raman c…

Spin-Nematic Vortex States in Cold Atoms
Li Chen, Yunbo Zhang, Han Pu
The (pseudo-)spin degrees of freedom greatly enriches the physics of cold atoms. This is particularly so for systems with high spins (i.e., spin quantum number larger than 1/2). Fo…
