Abstract In order to perform a simple design of topological edge states, we construct two-dimensional triangular lattices with reversed scatterers and matrix materials. As the p and d orbits in the two lattices are reversed, the topologically trivial and non-trivial states can directly be formed without any intermediate transition. The topological edge states occur at the interface between the two lattices. Our simulation results have demonstrated the existence of the pseudospin states and the spin-locked propagation with topological protection and intense field localization at the boundary.

来自两个具有反转材料的简单三角形晶格的高度受限的拓扑边缘状态

摘要 为了实现拓扑边缘态的简单设计，我们构建了具有反向散射体和基体材料的二维三角形晶格。由于两个晶格中的 p 和 d 轨道颠倒，可以直接形成拓扑平凡和非平凡状态，无需任何中间跃迁。拓扑边缘状态出现在两个晶格之间的界面处。我们的模拟结果证明了赝自旋态和自旋锁定传播的存在，拓扑保护和边界处的强场定位。
