221. Non-quantization of Current in an Annular Bose-Einstein Condensate
Published: Date unknown
Authors: D L Feder, L A Collins, Charles W Clark
Abstract: The circulating states of a Bose-Einstein condensate confined in an annulus are investigated both analytically and numerically. It is demonstrated that while single-valuedness of the condensate wavefunction ensures the quantization of circulation in ...

222. Vortices, Rings, and Spherical Shells in Bose-Einstein Condensates. I. Case of Repulsive Nonlinearity
Published: Date unknown
Authors: L D Carr, Charles W Clark
Abstract: The stationary behavior of axisymmetric vortex and vortex-like states of a Bose-Einstein condensate are described numerically and analytically. Both extended and con?ned condensates are considered in the context of the nonlinear Schrodinger equation, ...
