Vortex solitons in Bose-Einstein condensates with spin-orbit coupling and Gaussian optical lattices (Q1739396)

The authors investigate the generation and stability of three-dimensional (3D) solitons in binary atomic Bose-Einstein condensates with spin-orbit coupling (SOC) and super-Gaussian optical lattices. Depending on the relative strength of SOC, the nonlinearity modulation parameter, and the lattice parameters, they observe stable solitons of the semi-vortex and mixed-mode type. In addition, the robustness of solitons in propagation and collisions is demonstrated.
