Annihilation of quantized vorticity in a trapped Bose-Einstein condensate via the scattering of density perturbations
We evaluate the extraction of angular momentum from quantized vortices in trapped Bose-Einstein condensates. Within a variational approach we show that the energy barrier between the ground state and the state containing an axisymmetric vortex can be crossed in a scattering process by density pertur...
