Abstract
The structure of a cylindrically trapped, dilute atomic Bose-Einstein condensate penetrated by a vortex line was computed within self-consistent mean-field theories. It was found that the vortex state is locally energetically stable in a nonrotating system even in the zero-temperature limit. The thermal gas concentrated in the vortex core exhibited a crucial effect in stabilizing the vortex state even at ultralow temperatures, due to a residual noncondensate fraction present in interacting systems in the zero-temperature limit.
