论文摘要
我们提出了一个电阻，电感器和电容器（RLC）电路，以理论上分析并完全模拟具有复杂跳跃的新型非富士Su-Schrieffer-Heeger（SSH）模型。我们通过利用电路的多功能性来制定其结构并研究其性质。可以从RLC电路的正常振荡模式中鉴定出丰富的物理特性，包括拓扑绕组数量和边缘状态和非弱者皮肤现象之间的高度可调的散装对应关系，该现象来自新型的复杂能量平面拓扑。本研究能够表明电路固有的宽广且具有吸引力的拓扑物理学，很容易被概括为许多赫尔米尔人和非弱者非平凡系统。
We propose an resistors, inductors and capacitors (RLC) electrical circuit to theoretically analyze and fully simulate a new type of non-Hermitian Su-Schrieffer-Heeger (SSH) model with complex hoppings. We formulate its construction and investigate its properties by taking advantage of the circuit's versatility. Rich physical properties can be identified in this system from the normal modes of oscillation of the RLC circuit, including the highly tunable bulk-edge correspondence between topological winding numbers and edge states and the non-Hermitian skin phenomenon originating from a novel complex energy plane topology. The present study is able to show the wide and appealing topological physics inherent to electric circuits, which is readily generalizable to a plenty of both Hermitian and non-Hermitian nontrivial systems.
