Vortex Dipole in a BEC with dipole-dipole interaction

Vortex Dipole in a BEC with dipole-dipole interaction

We consider single and multiply charged quantized vortex dipole in an oblate dipolar Bose Einstein condensate in the Thomas-Fermi (TF) regime. We calculate the critical velocity for the formation of a pair of vortices of opposite charge. We find that dipolar interactions decrease the critical veloci...

Zusammenfassung:We consider single and multiply charged quantized vortex dipole in an oblate dipolar Bose Einstein condensate in the Thomas-Fermi (TF) regime. We calculate the critical velocity for the formation of a pair of vortices of opposite charge. We find that dipolar interactions decrease the critical velocity for a vortex dipole nucleation.
