Abstract
By numerically solving the Gross-Pitaevskii equation with phenomenological dissipation term, we study the vortex formation properties of a three-dimensional dipolar Bose-Einstein condensate of $^{164}$Dy atoms. We studied the influence of the contact interaction between atoms on the formation mechanism of vortex. We also study how the dipole orientation affects the vortex formation properties and the number of vortices. We find that enhancing the interaction of short-range repulsion interaction or dipolar repulsion interaction can shorten the time to form a stable vortex structure and increase the number of vortices.
