Ground state of spin-2 dipolar rotating Bose-Einstein condensates

We study the ground state of spin-2 dipolar rotating Bose-Einstein condensates in a harmonic potential. As the strength of dipolar interaction enhances, our results show that the vortex number becomes smaller and smaller at a fixed component. In addition, the vortex stripe occurs and its number increases. The components m(F) = +/- 1 or +/- 2 display the same density and the total density shows layered distribution. Increasing the rotational frequency to a higher value, the vortex number and vortex row number increase. We also plot the dependence of angular momentum L-z as a function of dipole strength c'(d), showing that L-z decreases with increasing c'(d).
