The Gross-Pitaevskii equation: Bäcklund transformations and admitted solutions (1803.09228v2)
Published 25 Mar 2018 in math-ph, math.AP, and math.MP
Abstract: B\"acklund transformations are applied to study the Gross-Pitaevskii equation. Supported by previous results, a class of B\"acklund transformations admitted by this equation are constructed. Schwartzian derivative as well as its invariance properties turn out to represent a key tool in the present investigation. Examples and explicit solutions of the Gross-Pitaevskii equation are obtained.
