论文摘要
量子力学的数学基础建立在线性代数上，而非线性操作员的应用可以在某些情况下导致出色的发现。在这封信中，我们提出了一个平方根高阶Weyl Semimetal（显示）的模型，该模型通过继承其母体汉密尔顿人的特征。发现这些节目既有“ Fermi-arc”表面和铰链状态，它们连接了Weyl点的投影。我们从理论上构建并在实验上观察了外来的，在三维（3D）堆叠的电路中，带有蜂窝状 - 卡加姆杂交和双螺旋互层耦合。我们的结果为在3D固态平台中实现方形拓扑开辟了大门。
The mathematical foundation of quantum mechanics is built on linear algebra, while the application of nonlinear operators can lead to outstanding discoveries under some circumstances. In this Letter, we propose a model of square-root higher-order Weyl semimetal (SHOWS) by inheriting features from its parent Hamiltonians. It is found that the SHOWS hosts both "Fermi-arc" surface and hinge states that connect the projection of the Weyl points. We theoretically construct and experimentally observe the exotic SHOWS state in three-dimensional (3D) stacked electric circuits with honeycomb-kagome hybridizations and double-helix interlayer couplings. Our results open the door for realizing the square-root topology in 3D solid-state platforms.
