摘要

通过数值求解具有现象学耗散项的Gross-Pitaevskii方程，研究了$^{164}$Dy原子的三维偶极玻色-爱因斯坦凝聚体的涡旋形成特性。研究了原子间的接触相互作用对涡旋形成机理的影响。我们还研究了偶极子取向对涡旋形成特性和涡旋数量的影响。我们发现，增强短程斥力相互作用或偶极斥力相互作用可以缩短形成稳定涡结构的时间，增加涡的数量。

Vortex Dynamics of a Three-dimensional Dipolar Bose-Einstein Condensate

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.
