We present the results of numerical calculations solving the 1D Gross-Pitaevskii equation and discuss the dynamics of dark and dark-bright solitons in Bose-Einstein condensates, particularly with regard to their collisions [1,2]. By tracing phase and densitydistribution of the condensate during the interaction, several types of collisions, depending on the depths of the solitons, can be distinguished. We compared these simulations with our results of the experimental observations of dark and dark-bright solitons in Bose-Einstein condensates. [1] C.
