Abstract

A hierarchy of the nonlocal nonlinear Schrödinger equation with self-consistent sources is introduced. The physically significant nonlinear equation is associated with the AKNS spectral problem. In the nonlocal case, the squared eigenfunction of the \(L\) operator leads to some changes in the term of the source that affect the motion of solitons. The soliton solutions of the nonlocal nonlinear Schrödinger equation with self-consistent sources are presented using the inverse scattering transform. The dynamics of the solitons are illustrated, which differ from those of the nonlocal equation without a source.

具有自洽源和动力学的非局部非线性薛定谔方程的层次结构

摘要介绍了具有自洽源的非局部非线性薛定谔方程的层次结构。物理上重要的非线性方程与 AKNS 谱问题相关。在非局部情况下，\(L\)算子的平方特征函数会导致影响孤子运动的源项发生一些变化。利用反散射变换给出了具有自洽源的非局部非线性薛定谔方程的孤子解。图示了孤子的动力学特性，与无源非局部方程的动力学特性不同。
