Multiple Solutions of the Gross-Pitaevskii-Equation in a gravitational field — •Zelimir Marojevic and Claus Lämmerzahl — Center of Applied Space Technology and Microgravity, Bremen

A new numerical method is used to treat the problem of a Bose-Einstein-Condensate in 3D trapped by a gravitational field along the axial direction and by a harmonic trap along the radial direction. We call this setup gravito-optical surface trap. This new algorithm gives us access to excited states, which belong to monkey type saddle points of the Lagrangian. In order to find a measure for gravitational acceleration the emerging pattern for different parameter sets are studied.
