(color online) Dynamical evolution of moving bright solitons for different velocities. The detuning is δ = 1.5, the SOC is γ = 1.5, and interaction strength is g = 1. Panels (a) and (b) represent the density and the phase of the bright solitons, respectively. The parameter for panels (a1) and (a2) is v = 0.001, and that for panels (a3) and (a4) is v = 3.
