Abstract

In this paper, a variational integrator is constructed for Gross-Pitaevskii equations in Bose-Einstein condensate. The discrete multi-symplectic geometric structure is derived. The discrete mass and energy conservation laws are proved. The numerical tests show the effectiveness of the variational integrator, and the performance of the proved discrete conservation law.
