Quantized vortices are the hallmark of superfluidity, and are often sought out as the first observable feature in new superfluid systems. Following the recent experimental observation of vortices in Bose-Einstein condensates comprised of atoms with inherent long-range dipole-dipole interactions [Nat. Phys. 18, 1453-1458], we thoroughly investigate vortex properties in the three-dimensional dominantly dipolar regime, where beyond-mean-field effects are crucial for stability, and investigate the interplay between trap geometry and magnetic field tilt angle.Résumé. Les vortex quantiques sont un marqueur fort de la superfluidité, et sont souvent recherchés comme première caractéristique observable dans les nouveaux systèmes superfluides. Suite aux récentes observations de vortex dans des condensats de Bose-Einstein constitués d'atomes en interaction intrinsèquement à longue portée [Nat. Phys. 18, 1453Phys. 18, -1458Phys. 18, (2022], nous étudions en détail les propriétés des vortex dans le régime dominé par les interactions dipolaires tridimensionnelles et dont la stabilité dépend crucialement des effets au-delà du champ moyen, et nous étudions l'influence de la géométrie du piège et de l'angle d'inclinaison du champ magnétique.

“…In this work the host medium is a Bose-Einstein condensate, however, our results can be easily extrapolated to impurities immersed in an isolated droplet or in a dipolar supersolid. A possible interesting future direction is to study the polaron dynamics across the superfluid-tosupersolid transition using dipolar or non-dipolar impurities embedded in dipolar media [58,59]. This transition is expected to have an unusual phase diagram [60], and the impurity dynamics may provide a tool to probe it.…”

We study the out-of-equilibrium quantum dynamics of dipolar polarons, i.e., impurities immersed in a dipolar Bose-Einstein condensate, after a quench of the impurity-boson interaction. We show that the dipolar nature of the condensate and of the impurity results in anisotropic relaxation dynamics, in particular, anisotropic dressing of the polaron. More relevantly for cold-atom setups, quench dynamics is strongly affected by the interplay between dipolar anisotropy and trap geometry. Our findings pave the way for simulating impurities in anisotropic media utilizing experiments with dipolar mixtures.
