We consider a dipolar Bose-Einstein condensate confined in an annular potential, with all the dipoles being aligned along some arbitrary direction. In addition to the dipole-dipole interaction, we also assume a zero-range hard-core potential. We investigate the stability of the system against collapse, as well as the stability of persistent currents as a function of the orientation of the dipoles and of the strength of the hard-core interaction.

Two-component dipolar Bose-Einstein condensate in concentrically coupled annular traps
TLDR
This work investigates the ground-state and rotational properties of a rotating two-component dipolar Bose-Einstein condensate, which consists of both dipolar bosonic atoms with magnetic dipole moments aligned vertically to the condensates and one without dipole Moments, confined in concentrically coupled annular traps.
Exotic vortex structures of the dipolar Bose–Einstein condensates trapped in harmonic-like and toroidal potential
Abstract Based on the tunable intensity and waist of Gaussian laser, harmonic-like and toroidal potentials can be achieved and the ground-state properties of the dipolar Bose–Einstein condensate

The purpose of this overview paper, which can be viewed as a supplement to our previous review on quantum rings [S. Viefers et al., Physica E 21 (2004), 1-35), is to highlight the differences of
Persistent currents in toroidal dipolar supersolids
We investigate the rotational properties of a dipolar Bose-Einstein condensate trapped in a toroidal geometry. Studying the ground states in the rotating frame and at fixed angular momenta, we
