Bose-Einstein-Condensates in the gravitational field — •Zelimir Marojevic and Claus Lämmerzahl — ZARM - Universität Bremen

We are studying numerically the eigenvalue problem for the Gross-Pitaevskii-Equation in a 1D configuration in the gravitational field for various situations. The most simple case is the Gravito-Optical Surface Trap configuration for the Gross-Pitaevskii-Equation with coupling to a homogeneous gravitational field and with a one-sided boundary condition. Characteristic properties of the solutions are investigated with respect to mass, gravitational acceleration and interaction strength. Further 1D configurations like Bose-Einstein Condensates restricted to a parabolic line are also studied.
