(color online) (a1), (b1) The first bright soliton component density of the SOC BEC for the nonzero detuning case. (a2), (b2) The second bright soliton component. The blue solid lines are variational method results, and the red dotted lines are the numerical densities by the imaginary time evolution method. In panels (a) and (b) the SOC is δ = 0.01, 0.5, respectively. The other parameters for panels (a) and (b) are g = 1, Ω² = 0.02, and γ = 1.
