摘要 得到了囚禁在平方双曲正切势中准一维非线性薛定谔方程的一个新的精确孤子解.在外部囚禁势下,当粒子之间的相互作用是排斥时,存在暗亮孤子解,以及通过解析的方法研究了它们的稳定性. The exact soliton solutions of the quasi-one-dimensional nonlinear Schrodinger equation with a square-tanh potential is investigated.Both the dark soliton and the bright soliton for the repulsive interparticle interaction are found under the existence of the external confining potential.Their stability is examined using analytical method.
