Phys. Rev. A 72, 053617 (2005) [7 pages]Stability of the solutions of the Gross-Pitaevskii equationReceived 19 July 2005; published 17 November 2005 We examine the static and dynamic stability of the solutions of the Gross-Pitaevskii equation and demonstrate the intimate connection between them. All salient features related to dynamic stability are reflected systematically in static properties. We find, for example, the obvious result that static stability always implies dynamic stability and present a simple explanation of the fact that dynamic stability can exist even in the presence of static instability. © 2005 The American Physical Society URL:
