Structure of vortices in rotating Bose-Einstein condensates
We calculate the structure of individual vortices in rotating Bose-Einstein condensates in a transverse harmonic trap. Making a Wigner-Seitz approximation for the unit cell of the vortex lattice, we derive the Gross-Pitaevskii equation for the condensate wave function in each cell of the lattice, including effects of varying coarse grained density. We calculate the Abrikosov parameter, the frac...
متن کاملVortices in Bose-Einstein Condensates
A Bose-Einstein condensate (BEC) was only experimentally realised in 1995. Research into nonlinear phenomenon (such as vortices) that exist in a BEC is thus in its infancy and a full understanding of how vortices move and interact is still lacking. A Bose-Einstein condensate is described by the GrossPitaevskii (GP) equation, a semi-classical non-linear PDE, given in terms of a wavefunction. In ...

متن کاملVortices in atomic-molecular Bose–Einstein condensates
The structure and stability of vortices in hybrid atomic-molecular Bose–Einstein condensates is analysed in the framework of a two-component Gross–Pitaevskii-type model that describes the stimulated Raman-induced photoassociation process. New types of topological vortex states are predicted to exist in the coherently coupled two-component condensates even without a trap, and their nontrivial dy...
متن کاملVortices in Bose-Einstein Condensates: Theory
Vortices are pervasive in nature, representing the breakdown of laminar fluid flow and hence playing a key role in turbulence. The fluid rotation associated with a vortex can be parameterized by the circulation Γ = ∮ dr · v(r) about the vortex, where v(r) is the fluid velocity field. While classical vortices can take any value of circulation, superfluids are irrotational, and any rotation or an...
