Stability criterion for attractive Bose-Einstein condensates

Berge, Lars I; Alexander, Tristram J; Kivshar, Yuri


In this study, an attempt was made to discriminate the different regions of collapse/no-collapse for the nonstationary solutions of the Gross-Pitaevskii equation. Exact conditions under which stationary localized states of the equation can exist were determined. In general, the stability of condensates from their particle numbers was determined directly.
