Chinese Abstract

本文運用數值模擬方法解耦合薛定諤方程,研究了常規勢阱中的局部畸變對多個玻色-愛因斯坦凝聚(BEC)孤子的演化及相互作用特性的影響,發現勢阱的局部畸變對BEC孤子的演化及相互作用的影響依賴於畸變的強度和畸變的性質,與常規勢阱的幅度、BEC孤子系統的參數及初始條件有密切的關係。

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.
