(color online) The fundamental properties of bright–bright solitons versus main parameters of the SOC-BEC system for the nonzero detuning case. Panels (a) and (b) show the relation of these properties with the detuning δ. The meanings of these defined parameters: distance, height, node, and width, are the same as those used in Fig. 2. The other parameters of panels (a) and (b) are γ = 1.0, Ω² = 0.02, and g = 1.0. The red circle marked in panel (b) is related to the density modes in Fig. 3.
