Generating vortex rings in Bose-Einstein condensates in the line-source approximation

A method was developed to study vortex rings hosted in confined condensates in the Thomas-Fermi limit. The velocity around the vortex core was introduced as an external field in the Gross-Pitaevskii energy functional. The density profile and nucleation energy of vortex rings in one-component condens...
