Rotational properties of dipolar Bose-Einstein condensates confined in anisotropic harmonic potentials

TL;DR

This paper investigates how the rotational behavior of dipolar Bose-Einstein condensates in anisotropic traps depends on interaction strengths, dipole orientation, and trap deformation, revealing complex state dependencies.

Contribution

It provides a detailed analysis of the influence of dipolar interactions and trap anisotropy on the ground state properties of dipolar BECs under rotation.

Findings

The lowest-energy state varies with dipolar and contact interaction strengths.

Orientation of dipoles significantly affects the condensate's properties.

Trap deformation influences the system's rotational states.

Abstract

We study the rotational properties of a dipolar Bose-Einstein condensate confined in a quasi-two- dimensional anisotropic trap, for an arbitrary orientation of the dipoles with respect to their plane of motion. Within the mean-field approximation we find that the lowest-energy state of the system depends strongly on the relative strength between the dipolar and the contact interactions, as well as on the size and the orientation of the dipoles, and the size and the orientation of the deformation of the trapping potential.
