We explore the time evolution of BEC condensates under different condition by solving the time-dependent nonlinear Schr?dinger equation (NLSE) that describes an inhomogeneous, weakly interacting Bose-Einstein condensate at zero temperature. We present numerical results of interference of two condensates which have different number of atoms in them and examine the evolution of a Bose-Einstein condensate which has split into two parts.
