论文摘要
我们提出了拓扑晶体绝缘子的宏伟类似物，该模拟物具有由时间反转和半翻译的组合对称性保护的狄拉克表面状态。构建了拓扑镁质系统的模型，我们证明了能量电流响应于电场的系统流动，这是由于带有旋转摩肌锁定的狄拉克表面状态。我们还提出了具有单斜结构的磁化合物CRI $ _ {3} $中拓扑结晶绝缘子的宏观类似物的实现。
We propose magnonic analogs of topological crystalline insulators which possess Dirac surface states protected by the combined symmetry of time-reversal and half translation. Constructing models of the topological magnon systems, we demonstrate that the energy current flows through the systems in response to an electric field, owing to the Dirac surface states with the spin-momentum locking. We also propose a realization of the magnonic analogs of topological crystalline insulators in a magnetic compound CrI$_{3}$ with a monoclinic structure.
