Vortex precession in a rotating nonaxisymmetric trapped Bose-Einstein condensate

Fetter, Alexander L. · Kim, Jong-kwan

Original · EN

We study the precession of an off-axis straight vortex in a rotating nonaxisymmetric harmonic trap in the Thomas-Fermi (TF) regime. A time-dependent variational Lagrangian analysis yields the dynamical equations of the vortex and the precessional angular velocity in two-dimensional (2D) and three-dimensional (3D) condensates.
