摘要 本文运用数值模拟方法解耦合薛定谔方程,研究了常规势阱中的局部畸变对多个玻色一爱因斯坦凝聚(BEC)孤子的演化及相互作用特性的影响,发现势阱的局部畸变对BEC孤子的演化及相互作用的影响依赖于畸变的强度和畸变的性质,与常规势阱的幅度、BEC孤子系统的参数及初始条件有密切的关系。 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 fotmd 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.
