Abstract

We derive an analytic expression for the phase of a quantum vortex in a dipolar Bose-Einstein condensate, capturing anisotropic effects from long-range dipole-dipole interactions. This solution provides a foundation for a dipolar point vortex model (DPVM), incorporating both phase-driven flow and dipolar forces. The DPVM reproduces key features of vortex pair dynamics seen in full simulations, including anisotropic velocities, deformed orbits, and directional motion, offering a minimal and accurate model for dipolar vortex dynamics. Our results open the door to analytic studies of vortices in dipolar quantum matter and establish a platform for exploring vortex dynamics and turbulence in these systems.

  58. We have verified that we can obtain the same results taking the real space form of the quasi-2D dipole-dipole interaction [54]; however, the final expressions are much longer, and the agreement between GPE and DPVM persists (not shown). In addition, we have verified that taking a regularization parameter Δ such that ρ3→(ρ3+Δ) [64] does not affect our results, due to the fact that the vortices in our model are well separated, and Δ only becomes important close to the vortex core.
