非线性物理中一类新的具有可预报性的无赖波

A novel type of rogue waves with predictability in nonlinear physics

M. Jia, S. Y. Lou

摘要:

由海洋学家命名的流氓波在自然界中是普遍存在的,并出现在各种不同的情况下,如水波,液氦,非线性光学,微波腔等,在这封信中,我们提出了一种新的类型的精确的(2+1)维流氓波,它可能会发现在许多物理领域所描述的可积和不可积模型。这种类型的流氓波与看不见的肿块密切相关。通常,肿块是空间中的代数局域波,但在任何时候都可见。当一个光团诱导出一个孤立子时,光团将在一个固定的时间之前或之后变得不可见。如果一个有界孪生孤子是由一个块诱导的,那么这个块将成为一个无赖波(或瞬子),并且只能在瞬间可见。由于可见光孤子的存在,在一定程度上可以预测无赖波。例如,流氓波的高度、位置和到达时间是可以预测的。这个想法是说明庆祝(2+1)维Kadomtsev-Petviashvili方程在其扩展形式。

英文摘要:

Rogue waves named by oceanographers are ubiquitous in nature and appear in a variety of different contexts such as water waves, liquid Helium, nonlinear optics, microwave cavities, etc. In this letter, we propose a novel type of exact (2+1)-dimensional rogue waves which may be found in many physical fields described by integrable and nonintegrable models. This type of rogue waves are closely related to invisible lumps. Usually, a lump is an algebraically localized wave in space but visible at any time. Whence a lump induces a soliton, the lump will become invisible before or after a fixed time. If a bounded twin soliton is induced by a lump, the lump will become a rogue wave (or instanton) and can only be visible at an instant time. Because of the existence of the induced visible solitons, the rogue wave may be predictable in some senses. For instance, the height, the position and the arrival time of the rogue wave can be predictable. The idea is illustrated by the celebrate (2+1)-dimensional Kadomtsev-Petviashvili equation in its extended form.
