多分量AB系统的暗孤子解

Bright-dark soliton solutions to the multi-component AB system

Zong-Wei Xu, Guo-Fu Yu, Zuo-Nong Zhu

摘要:

本文研究了由地球物理流体动力学导出的多分量AB系统。利用Hirota的双线性方法构造了亮暗孤子解。对于两分量AB系统,得到了两孤子解的渐近性质,证明了两亮孤子和两暗孤子之间的相互作用是弹性的。在不同的参数条件下,详细分析了孤子的斜交相互作用和束缚态。同时,利用Pfuman方法,我们给出了两分量和多分量AB系统的$N$-亮孤子解和$N-$暗孤子解。该结果对于研究非线性光学、流体动力学等物理系统中的矢量多暗孤立子具有重要意义。

英文摘要:

In this paper we investigate the multi-component AB system that comes from the geophysical fluid dynamics. We construct bright-dark soliton solutions through Hirota's bilinear method. For the two-component AB system, asymptotic behaviours of two-soliton solution are obtained and interactions between two bright and two dark solitons are proved to be elastic. Under different parameter conditions, the oblique interactions, bound states of solitons are analyzed in details. Meanwhile, by use of the Pfaffian technique, we present $N$-bright and $N-$dark soliton solutions to the two- and multi-component AB system. The results will be meaningful for the study of vector multi-dark solitons in many physical systems such as nonlinear optics and fluid dynamics.
