English Abstract

The effects of the localized impurity in a conventional potential on the characteristics of the evolution and interaction of a few Bose-Einstein Condensate (BEC) solitons are investigated by direct numerical simulations of the coupling Nonlinear Schrodinger equations. It is found that such effects depend on the strength and features of the impurity, and are related to the amplitude of the trapping potential, the parameters of the BEC soliton system and the initial condition.
