Abstract

GSGPEs is a Matlab/GNU Octave suite of programs for the computation ofthe ground state of systems of Gross–Pitaevskii equations. It can computethe ground state in the defocusing case, for any number of equations withharmonic or quasi-harmonic trapping potentials, in spatial dimension one,two or three. The computation is based on a spectral decomposition ofthe solution into Hermite functions and direct minimization of the energyfunctional through a Newton-like method with an approximate line-searchstrategy.
