Figure 1. The ground-state density profiles of rotating spin-1/2 BECs loaded in a harmonic plus quartic trap with gradient magnetic field. The columns in every panel from left to right are the densities of spin-$\uparrow $ component, spin-$\downarrow $ component, total and difference. The upper row with rotation strength ω = 1, the magnetic field gradient strengths B = 0 in (a) and B = 10 in (b). The lower row with rotation strength ω = 1.4, the magnetic field gradient strengths B = 0 in (c) and B = 10 in (d).
