Abstract

We show that a multiply quantized vortex line core can be energetically stable in a harmonically trapped two-component atomic Bose-Einstein condensate. The structure, in which the condensate component with the vortex line is surrounded by the second component forming a vortex ring, can be identified as a particlelike skyrmion with a multiply quantized winding number, and closely resembles cosmic vortons.
