Anca Visinescu, Dan Grecu, Renato Fedele, Sergio De Nicola

摘要:

利用多尺度方法研究了两个亮孤子和一个暗孤子之间的相互作用。在满足长波-短波共振条件下,得到了两分量Zakharov-Yajima-Oikawa(ZYO)完全可积系统.利用Madelung流体描述,确定了相应ZYO系统的单孤子解。此外,还讨论了一个亮孤子和两个暗孤子之间的相互作用。特别是,这个问题被减少到解决一个组件ZYO系统的共振条件。

英文摘要:

Using the multiple scales method, the interaction between two bright and one dark solitons is studied. Provided that a long wave-short wave resonance condition is satisfied, the two-component Zakharov-Yajima-Oikawa (ZYO) completely integrable system is obtained. By using a Madelung fluid description, the one-soliton solutions of the corresponding ZYO system are determined. Furthermore, a discussion on the interaction between one bright and two dark solitons is presented. In particular, this problem is reduced to solve a one-component ZYO system in the resonance conditions.
