Three Dimensional Simulation of Jet Formation in Collapsing Condensates
We numerically study the behavior of collapsing and exploding condensates
using the parameters of the experiments by E.A. Donley et al. [Nature,
412, 295, (2001)]. Our studies are based on a full three-dimensional
numerical solution of the Gross-Pitaevskii equation (GPE) including three body
loss. We determine the three body loss rate from the number of remnant
condensate atoms and collapse times and obtain only one possible value which
fits with the experimental results. We then study the formation of jet atoms by
interrupting the collapse and find very good agreement with the experiment.
Furthermore we investigate the sensitivity of the jets to the initial
conditions. According to our analysis the dynamics of the burst atoms is not
described by the GPE with three body loss incorporated.Comment: 9 pages, 10 figure
