Autosolitons in trapped Bose-Einstein condensates with two- and three-body inelastic processes
arXiv:cond-mat/0010152 · doi:10.1103/PhysRevA.63.053603
Abstract
In this work, we consider the conditions for the existence of autosolitons, in trapped Bose-Einstein condensates with attractive atomic interactions. First, the variational approach is employed to estimate the stationary solutions for the three-dimensional Gross-Pitaevskii equation with trap potential, linear atomic feeding from the thermal cloud and two- and three-body inelastic processes. Next, by using exact numerical calculations, we show that the variational approach gives reliable analytical results. We also discuss the possible observation of autosolitons in experiments with Lithium-7.
