摘要
We investigate the collision of two oblique dark solitons in the two-dimensional supersonic nonlinear Schrodinger flow past two impenetrable obstacles. We numerically show that this collision is very similar to the dark solitons collision in the one-dimensional case. We observe that it is practically elastic and we measure the shifts of the solitons positions after their interaction. (C) 2011 Elsevier B.V. All rights reserved.
