论文摘要
我们构建了一个电路，以实现一个改良的haldane晶格，表现出抗酸边缘状态的异常现象。该电路由具有互连的电感器和电容器网络组成，该网络再现了磁性矢量电位的影响。下一个最近的邻居跳的配置与标准haldane模型的配置不同，并且如前所述的理论研究所预测，这会导致抗酸边缘状态，这些状态在相反的边缘在相同方向上传播，并在相同频率的相同频率上共存。使用拾音器线圈测量电路中的电压分布，我们通过实验验证了修改后的Haldane晶格的关键特征，包括抗病毒边缘状态的组速度。
We constructed an electrical circuit to realize a modified Haldane lattice exhibiting the unusual phenomenon of antichiral edge states. The circuit consists of a network of inductors and capacitors with interconnections reproducing the effects of a magnetic vector potential. The next nearest neighbor hoppings are configured differently from the standard Haldane model, and as predicted by earlier theoretical studies, this gives rise to antichiral edge states that propagate in the same direction on opposite edges and co-exist with bulk states at the same frequency. Using pickup coils to measure the voltage distributions in the circuit, we experimentally verify the key features of the modified Haldane lattice, including the group velocities of the antichiral edge states.
