00925njm 22002777a 4500 dc Makarov Slizneva, Valeriy author Velarde, Manuel G. author Guoxiang, Huang author 2001-07 The evolution and collision of dark solitary waves (solitons) appearing in cigar-shaped Bose-Einstein condensates with repulsive atom-atom interaction are here considered using a Boussinesq-Korteweg-de Vries description. 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 1050-2947 10.1103/PhysRevA.64.013617 https://hdl.handle.net/20.500.14352/57667 http://pra.aps.org/pdf/PRA/v64/i1/e013617 http://pra.aps.org/ Dark solitons and their head-on collisions in Bose-Einstein condensates
