The formation of quantized vortices in trapped, gaseous Bose-Einstein condensates is considered. The thermodynamic stability of vortex states and the essential role of the surface excitations as a route for vortex penetration into the condensate are

Quantization of the circulation of superflow is considered for periodic vortex textures in the rotating A phase of superfluid 3He. The quantization rule is derived by the application of symmetry principles alone.

Quantum-dynamic processes of phase slippage in3He are demonstrated to be associated with superfluid vortex nucleation, thus confirming Anderson's scenario for phase slippage through vortex generation and motion in superfluids. We also encounter more

Time-dependent Ginzburg-Landau theory is used to compute a generalized current-phase relation for superfluid 3He flow driven by a chemical-potential difference. Our numerical simulations reveal a tendency for avalanches of vortices to appear practica

Quantized vortices in superfluid3He display a variety of novel structures that have previously not been observed in any other quantum fluids; their basic experimental manifestations and theoretical features have been reviewed by Hakonen, Lounasmaa an

A new first-order phase transition is proposed to manifest itself in rotating 3He-B for the vortex-free state, owing to counterflow. The 'flare-out' texture is found to become spontaneously unstable towards a new 'flare-in' texture, which is suggeste

We study the stability of vortices in trapped single-component Bose-Einstein condensates within self-consistent mean-field theories--especially we consider the Hartree-Fock-Bogoliubov-Popov theory and its recently proposed gapless extensions. It is s

We compute structures of vortex configurations in a harmonically trapped Bose-Einstein condensed atom gas within three different gapless self-consistent mean-field theories. Outside the vortex core region, the density profiles for the condensate and
