本文主要研究可积的耦合Sasa-Satsuma方程,它可用于描述两个超短脉冲在双折射或双模光纤中的传输动力学.通过Darboux-穿衣变换,可以得到一类半有理解.这类解能够展示出怪波与呼吸波之间各种有趣的叠加场景.这些结果将有助于丰富和解释出现在光纤和色散介质中一些相关的非线性现象. 相似文献

Under investigation in this work is the general coupled nonlinear Schrödinger (gCNLS) equation, which can be used to describe a wide variety of physical processes. By using Darboux transformation, the new higher-order rogue wave solutions of the equation are well constructed. These solutions exhibit rogue waves on a multi-soliton background. Moreover, the dynamics of these solutions is graphically discussed. Our results would be of much importance in enriching and predicting rogue wave phenomena arising in nonlinear and complex systems. 相似文献
