(color online) [(a1), (b1), and (c1)]: The first moving bright soliton state density of an SOC–BEC. [(a2), (b2), and (c2)]: The second moving bright soliton. The solid lines are numerical results, and the dotted lines are the variational densities. The parameters for all panels (a), (b), and (c) are g = 1, v = 0.001, and δ = 0. In panels (a), (b), and (c) γ = 0.5, 1.5, 2.5 respectively.
