Vortices in Bose-Einstein Condensates
نویسنده
چکیده
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 a BEC a vortex is defined as a zero of this wavefunction. I consider various simulations on the GP equation in order to better understand the motion of vortices in BEC’s.

Vortex pump for dilute bose-einstein condensates.
The formation of vortices by topological phase engineering has been realized experimentally to create the first two- and four-quantum vortices in dilute atomic Bose-Einstein condensates. We consider a similar system, but in addition to the Ioffe-Pritchard magnetic trap we employ an additional hexapole field. By controlling cyclically the strengths of these magnetic fields, we show that a fixed ...
متن کاملKibble-Zurek scaling and its breakdown for spontaneous generation of Josephson vortices in Bose-Einstein condensates.
Atomic Bose-Einstein condensates confined to a dual-ring trap support Josephson vortices as topologically stable defects in the relative phase. We propose a test of the scaling laws for defect formation by quenching a Bose gas to degeneracy in this geometry. Stochastic Gross-Pitaevskii simulations reveal a -1/4 power-law scaling of defect number with quench time for fast quenches, consistent wi...
متن کاملSPECIAL FEATURE: PERSPECTIVE Vortices and turbulence in trapped atomic condensates
After more than a decade of experiments generating and studying the physics of quantized vortices in atomic gas Bose–Einstein condensates, research is beginning to focus on the roles of vortices in quantum turbulence, as well as other measures of quantum turbulence in atomic condensates. Such research directions have the potential to uncover new insights into quantum turbulence, vortices, and s...
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 کاملObservation of vortex pinning in Bose-Einstein condensates.
We report the observation of vortex pinning in rotating gaseous Bose-Einstein condensates. Vortices are pinned to columnar pinning sites created by a corotating optical lattice superimposed on the rotating Bose-Einstein condensates. We study the effects of two types of optical lattice: triangular and square. In both geometries we see an orientation locking between the vortex and the optical lat...
متن کاملVortices in attractive Bose-Einstein condensates in two dimensions.
The form and stability of quantum vortices in Bose-Einstein condensates with attractive atomic interactions is elucidated. They appear as ring bright solitons, and are a generalization of the Townes soliton to nonzero winding number m. An infinite sequence of radially excited stationary states appear for each value of m, which are characterized by concentric matter-wave rings separated by nodes...
