一类混合耦合非线性薛定谔系统的Riemann-Hilbert方法及其孤子解

Riemann-Hilbert approach for a mixed coupled nonlinear Schrödinger system and its soliton solutions

Fang Fang, Beibei Hu, Ling Zhang, Ning Zhang

摘要:

在这项工作中,我们研究了可积混合耦合非线性薛定谔(mCNLS)系统,它描述了光脉冲在双折射光纤中的传播。利用Riemann-Hilbert(RH)方法,当特定RH问题的跳变矩阵为$3\times3$单位矩阵时,mCNLS系统的N孤子解可以显式表示.作为特例,给出了单孤子和双孤子的表达式。更一般地,作为推广,讨论了可积的广义多分量NLS系统及其线性谱问题。我们希望我们的研究结果能有助于丰富mCNLS的非线性动力学行为。

英文摘要:

In this work, we examine the integrable mixed coupled nonlinear Schrödinger (mCNLS) system, which describe the propagation of an optical pulse in a birefringent optical fiber. By the Riemann-Hilbert(RH) approach, the N-soliton solutions of the mCNLS system can be expressed explicitly when the jump matrix of a specific RH problem is a $3\times3$ unit matrix. As a special example, the expression of one- and two-soliton are displayed explicitly. More generally, as a promotion, an integrable generalized multi-component NLS system with its linear spectral problem be discussed. It is hoped that our results can help enrich the nonlinear dynamical behaviors of the mCNLS.
