Manakov方程怪波的精确解析谱

Exact analytic spectra of rogue waves for Manakov equations

Shao-Chun Chen, Chong Liu, Nail Akhmediev

AI总结:

针对聚焦与散焦状态下的Manakov方程怪波,本文推导其精确解析谱,揭示非对称、对数尺度三角形及零频谱跳变等特征,并以数值模拟验证。

摘要:

本文以解析形式推导了在聚焦或散焦状态下均存在的Manakov方程怪波的谱。这些谱在其整个膨胀—收缩周期内都是非对称的。在对数尺度下,谱的每一侧均呈三角形。此类谱由两个量表征:谱的斜率以及零频率处的谱跳变。我们通过数值模拟证实了解析结果。

英文摘要:

The spectra of rogue waves of Manakov equations that exist in both focusing or defocusing regimes are derived in analytic form. These spectra are asymmetric during their whole expansion-contraction cycle. They have triangular shape at each side of the spectrum in the log scale. Such spectra are characterised by two quantities: the slopes of the spectra and the spectral jump at zero frequency. We confirm our analytical results using numerical simulations.
