Mobile vector soliton in a spin–orbit coupled spin-1 condensate
Mobile vector soliton in a spin–orbit coupled spin-1 condensate
We study the formation of bound states and three-component bright vector solitons in a quasi-one-dimensional spin–orbit-coupled hyperfine spin f = 1 Bose–Einstein condensate using numerical solution and variational approximation of a mean-field model. In the antiferromagnetic domain, the solutions are time-reversal symmetric, and the component densities have multi-peak structure. In …
