We report the universal emergence of anomalous fundamental Peregrine solitons, which can exhibit an unprecedentedly ultrahigh peak amplitude comparable to any higher-order rogue wave events, in the vector derivative nonlinear Schrödinger system involving the self-steepening effect. We present the exact explicit rational solutions on either a continuous-wave or a periodical-wave background, for a broad range of parameters. We numerically confirm the buildup of anomalous Peregrine solitons from strong initial harmonic perturbations, despite the onset of competing modulation instability. Our results may stimulate the experimental study of such Peregrine soliton anomaly in birefringent crystals or other similar vector systems.

矢量非线性系统中通过自加强实现超强幅度增强的基本游廊孤子

我们报道了在异常自激效应的矢量导数非线性Schrödinger系统中，异常基本Peregrine孤子的普遍出现，该孤子可以表现出前所未有的超高峰值幅度，可与任何高阶流浪事件相比。对于广泛的参数，我们在连续波或周期性波背景下给出了精确的显式有理解。我们从数值上证实了尽管竞争性调制不稳定性的开始，但强烈的初始谐波扰动会形成异常的百富勤孤子。我们的结果可能会刺激在双折射晶体或其他类似矢量系统中这种游Per孤子异常的实验研究。
