Collapse and three-body loss in a 85 Rb Bose-Einstein condensate

Altin, Paul; Dennis, Graham; McDonald, Gordon; Doering, Daniel; Debs, John; Close, John; Savage, Craig; Robins, Nicholas


Collapsing Bose-Einstein condensates are rich and complex quantum systems for which quantitative explanation by simple models has proved elusive. We present experimental data on the collapse of high-density 85Rb condensates with attractive interactions and find quantitative agreement with the predictions of the Gross-Pitaevskii equation. The collapse data and measurements of the decay of atoms from our condensates allow us to put new limits on the value of the 85Rb three-body loss coefficient...[Show more]
