Numerical simulation of a spinor Bose-Einstein condensate.

Abstract

The two-spin components Bose-Einstein condensate in simulated in an anisotropic harmonic potential. A reduced two-dimensional model for this system is developed. The ground state of the model is shown. In order to check the validity of the simulation the size of the interface of the condensate and the speed of sound in the condensate are calculated. The result show that the simulation correctly predicts the behavior of the BEC. The time evolution of the two-spin component Bose-Einstein condensate is investigated for a symmetrical and asymmetrical initial conditions. The results show that the components do not mix and slide past each other. The simulation predicts that the interface is turbulent during movement, but this might be due to the absence of dampening by a thermal cloud in the simulation.
