Figure 2. Three different density profiles for the KDCSs in three-component coupled systems. (a1)–(a4) The density profiles of a droplet-bubble-droplet with a density dip. It corresponds to the blue triangle in figure 1. The parameters are φ1 = 0.93π and φ2 = 0.5φ1. (b1)–(b4) The density profiles of a dark soliton located on the left side of a bubble-droplet-bubble. It corresponds to the red circle in figure 1. The parameters are φ1 = 0.1π and φ2 = 0.9π. (c1)–(c4) The density profiles of the general form of KDCSs. It corresponds to the black pentagram in figure 1. The parameters are φ1 = 0.5π and φ2 = 0.3π. The red dashed–dotted line, blue dotted line, green dashed line and black solid line correspond to the density distributions of component q1, component q2, component q3, and sum of them respectively. The other parameters are setting same as in figure 1.
