标题： Angular momentum-dependent topological transport and its experimental realization using a transmission line network

摘要： 新型经典波现象类比量子自旋霍尔效应主要基于赝自旋的构造。 在这里，我们表明，通过角动量轨道耦合，也可以使用轨道角动量来实现系统的非平凡拓扑。 这个想法通过一个紧束缚模型进行说明，并通过传输线网络进行实验演示。 我们实验证明，即使是一个非常小的网络簇也表现出单向拓扑边缘态，其特性可以用局部陈数来描述。 我们的工作为在经典波中实现量子自旋霍尔效应的对应现象提供了一种新机制，并可能为其他系统提供见解。 显示英文摘要

摘要： Novel classical wave phenomenon analogs of the quantum spin Hall effect are mostly based on the construction of pseudo-spins. Here we show that the non-trivial topology of a system can also be realized using orbital angular momentum through angular-momentum-orbital coupling. The idea is illustrated with a tight-binding model and experimentally demonstrated with a transmission line network. We show experimentally that even a very small network cluster exhibits one-way topological edge states, and their properties can be described in terms of local Chern numbers. Our work provides a new mechanism to realize counterparts of the quantum spin Hall effect in classical waves and may offer insights for other systems.
