We provide theoretical predictions and computer experiment evidence about their phase shifts or change of trajectories, in the space-time plot, corresponding upon collisions. Details are also given about a suggested experiment that could assess their genuine solitonic nature eng open access Dark solitons and their head-on collisions in Bose-Einstein condensates journal article
