We investigate the phenomenon of resonant radiation emitted by Peregrine solitons. We show that, unlike bright or dark solitons of the nonlinear Schrödinger equation, the radiation process is affected by the intrinsic local longitudinal variation of the soliton wavenumber. We give a phase-matching condition that allows the prediction of the multiple spectral peaks of the resonant radiation.

百富勤孤子的共振辐射

我们研究了百富勤孤子发出的共振辐射现象。我们证明，与非线性Schrödinger方程的亮或暗孤子不同，辐射过程受孤子波数的固有局部纵向变化影响。我们给出了一个相位匹配条件，可以预测共振辐射的多个光谱峰。
