标题： Experimental study of Su-Schrieffer-Heeger edge modes for water waves in linear and nonlinear regime

摘要： 本文通过直接几何映射到一维苏-施里弗-黑格（SSH）模型，实验研究了水波通道中的拓扑保护边缘模式。 通过设计具有交替宽度的周期性通道，我们复现了SSH模型的关键特征，从而在边界处出现了稳健的零能晃动边缘模式。 实验数据与理论预测高度一致，得到了二维数值模拟的支持。 在非线性 regime 中，观察到两种不同的分叉，表明次级共振的出现。 本研究突显了SSH模型在水波系统中的相关性，并提供了一种可访问的方法来探索经典波系统中的拓扑边缘态。 显示英文摘要

摘要： This paper experimentally investigates topologically protected edge modes in a water wave channel through a direct geometric mapping to the one-dimensional Su-Schrieffer-Heeger (SSH) model. By designing a periodic channel with alternating widths, we replicate the key features of the SSH model, leading to the emergence of robust zero-energy sloshing edge modes localized at the boundaries. Experimental data show excellent agreement with theoretical predictions, supported by two-dimensional numerical simulations. In the nonlinear regime, two distinct bifurcations are observed, indicating the appearance of secondary resonances. This study highlights the relevance of the SSH model for water wave systems and provides an accessible method to explore topological edge states in classical wave systems.
