摘要:

本文详细研究了在流体力学和光学领域中观测到的有理呼吸波的相位特性,即游子孤子和相关的二阶解。在最大压缩点,我们的实验结果记录在一个波槽或使用光纤平台揭示了一个特征相移是$π$的脉冲的中心部分和连续的背景之间的倍数,在协议与分析和数值预测。我们还强调存在一个大的纵向相移的最大压缩点。

英文摘要:

We present a detailed study of the phase properties of rational breather waves observed in the hydrodynamic and optical domains, namely the Peregrine soliton and related second-order solution. At the point of maximum compression, our experimental results recorded in a wave tank or using an optical fiber platform reveal a characteristic phase shift that is multiple of $π$ between the central part of the pulse and the continuous background, in agreement with analytical and numerical predictions. We also stress the existence of a large longitudinal phase shift across the point of maximum compression.
