Fig. 1. Schematic two-domain structures for a a ferromagnetic spinor BEC with zero total spin and c a spin-imbalanced ferromagnetic spinor BEC. Dotted, dashed, and solid lines represent the particle distributions of M F #cod#x0003D; #cod#x000B1; 1 and M F = 0 bosons, respectively. Panels b and d show the simplified domain structures. Each component has a constant distribution within the domain structure, and the distribution of the M F = 0 bosons is a constant throughout the entire system. The gray region denotes the domain wall. The density distribution shown in the figure is #cod#x003C1; r , t #cod#x0003D; N a t #cod#x003B7; a r , t , and V #cod#x002B; and V #cod#x2013; are the sizes of the two domain structures.
