What is recorded here?
In 2000 Madison and colleagues used a rotating laser perturbation of a trapped rubidium Bose-Einstein condensate to observe one to four vortices and study their frequency-dependent appearance and lifetime. In 2001 Abo-Shaeer and colleagues stirred a sodium condensate and imaged ordered triangular arrays with up to about 130 vortices, as well as defects and their evolution. These related observations used different teams, atoms and conditions.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Both studies inferred vortex structures from absorption images after expansion rather than directly imaging a complete in-trap three-dimensional state. Madison and colleagues found the observed onset above their quoted simple predicted threshold, nonexponential single-vortex survival and shot-to-shot fluctuations in the multiple-vortex region; the nucleation and loss mechanisms were not uniquely determined. The later large lattice showed finite lifetimes and defects, and its nucleation mechanism likewise remained open. Earlier phase-engineered two-component vortices are a separate contribution. The two distinct author lists and experimental conditions remain separate.
