The ground states and pseudospin textures of rotating two-component Bose–Einstein condensates trapped in harmonic plus quartic potential
Liu Yan, Zhang Su-Ying†,
       

The pseudospin densities distributions and the relative phases for different r0: (a) r0 = 1, (b) r0 = 5, and (c) r0 = 7. The first row is Sx, the second row is Sy, the third row is Sz, and the fourth row is the relative phases θ1 − θ2.
