Multiple solutions of the time-independent Gross-Pitaeskii equation — •Želimir Marojević, Ertan Göklü, and Claus Lämmerzahl — ZARM - Center of Applied Space Technology and Microgravity, Bremen

We present a new algorithm which is capable to find saddle point solutions of the Gross-Pitaeskii action for large nonlinearites. It turns out that some of these solutions have unexpected complex structures. This algorithm has been applied to different situations in 2D and 3D, i.e. BEC in a harmonic trap, gravitational trap and no trap with Dirichlet boundary conditions.
