Highly Controllable and Robust 2D Spin-Orbit Coupling for Quantum Gases
Highly Controllable and Robust 2D Spin-Orbit Coupling for Quantum Gases
We report the realization of a robust and highly controllable two-dimensional (2D) spin-orbit (SO) coupling with a topological nontrivial band structure. By applying a retro-reflected 2D optical lattice, phase tunable Raman couplings are formed into the antisymmetric Raman lattice structure, and generate the 2D SO coupling with precise inversion and …
