论文摘要
我们研究由Dzyaloshinskii-Moriya相互作用的梯度产生的量规场，并提出了AFM的磁子拓扑绝缘子的模型。在长波长极限中，由克莱因·戈登方程描述的相对论物理学表现出由不均匀的dzyaloshinskii-moriya相互作用引起的兰道水平。将由于形成镁质兰道水平的形成而引起的旋转响应与Skyrmion和AFM绝缘子的涡流 - 抗体晶体相的相似拓扑响应进行了比较。我们的研究表明，AFM绝缘子表现出与拓扑木兴激发相关的丰富物理学。
We study gauge fields produced by gradients of the Dzyaloshinskii-Moriya interaction and propose a model of AFM topological insulator of magnons. In the long wavelength limit, the Landau levels induced by the inhomogeneous Dzyaloshinskii-Moriya interaction exhibit relativistic physics described by the Klein-Gordon equation. The spin Nernst response due to the formation of magnonic Landau levels is compared to similar topological responses in skyrmion and vortex-antivortex crystal phases of AFM insulators. Our studies show that AFM insulators exhibit rich physics associated with topological magnon excitations.
