TL;DR
This paper investigates the ground state and collective oscillation modes of a spin-polarized dipolar Bose-Einstein condensate in an anisotropic harmonic trap, considering arbitrary magnetic field orientation.
Contribution
It provides new theoretical results on the condensate's properties when the magnetic field is not aligned with the trap axes.
Findings

Analyzed quadrupolar density oscillation modes in this configuration.
Extended understanding of dipolar BEC behavior in realistic trapping conditions.
Abstract
We report new results for the Thomas-Fermi groundstate and the quadrupolar modes of density oscillations of a spin- polarized dipolar interacting Bose-Einstein condensate for the case when the external magnetic field is not orientated parallel to a principal axis of a harmonic anisotropic trap.
