(color online) (a1), (b1) The first bright soliton component density of the SOC BEC. (a2), (b2) The second bright soliton component. The blue solid lines are the variational method results, and the red dotted lines are the numerical densities by the imaginary time evolution method. The SOC is γ = 1.0 and 0.2 for panels (a) and (b), respectively. The other parameters for panels (a) and (b) are g = 1, Ω² = 0.02, and δ = 0.
