Vector solitons in a spin-orbit-coupled spin-2 Bose-Einstein condensate

Vector solitons in a spin-orbit-coupled spin-2 Bose-Einstein condensate

Five-component minimum-energy bound states and mobile vector solitons of a spin-orbit-coupled quasi-one-dimensional hyperfine-spin-2 Bose-Einstein condensate are studied using the numerical solution and variational approximation of a mean-field model. Two distinct types of solutions with single-peak and multipeak density distribution of the components are identified in different domains of interaction parameters. …
