(color online) Dynamical evolution of bright solitons for different velocity in the case of zero detuning. The detuning is δ = 0, the SOC is γ = 1, the oscillator frequency is Ω² = 0.02, and interaction strength is g = 1. Top (bottom) panel: the first (second) bright solitons density evolution result. The moving velocity of bright solitons for panels (a1) and (a2) is v = 0.2, (b1) and (b2) is v = 0.5, (c1) and (c2) is v = 1.
