带导数的一般非线性薛定谔方程的两类异常波

Two kinds of rogue waves of the general nonlinear Schrödinger equation with derivative

Shuwei Xu, Jingsong He, Lihong Wang

摘要:

本文通过构造变系数导数非线性薛定谔方程(VCDNLSE)到通常的导数非线性薛定谔方程(DNLSE)的显式变换,证明了VCDNLSE的可设计可积性.带DI的VCDNLSE的一个新特点是它的系数可以通过变换人工解析地设计。此外,从DNLSE的无赖波和有理行波解出发,通过这种变换得到了VCDNLSE的两种无赖波。一种是边界条件为零的流氓波,另一种是边界条件为非零的流氓波。VCDNLSE的DI也提供了一种在物理实验中控制流氓波轮廓的可能方法。

英文摘要:

In this letter,the designable integrability(DI) of the variable coefficient derivative nonlinear Schrödinger equation (VCDNLSE) is shown by construction of an explicit transformation which maps VCDNLSE to the usual derivative nonlinear Schrödinger equation(DNLSE). One novel feature of VCDNLSE with DI is that its coefficients can be designed artificially and analytically by using transformation. What is more, from the rogue wave and rational traveling solution of the DNLSE, we get two kinds of rogue waves of the VCDNLSE by this transformation. One kind of rogue wave has vanishing boundary condition, and the other non-vanishing boundary condition. The DI of the VCDNLSE also provides a possible way to control the profile of the rogue wave in physical experiments.
