Magnetic interactions in topological electron systems

近年来，人们已经清楚地认识到，除了对称性之外，拓扑学在物质相的分类中也起着至关重要的作用。在拓扑阶段，缺陷经常与有趣和重要的物理相关联。在本项目中，我们建议研究拓扑相和磁性杂质的相互作用。我们将集中在以下方面：（一）螺旋边缘状态的量子自旋霍尔效应的系统，（二）拓扑超导体支持马约拉纳费米子，（三）超导体中的Shiba束缚态，（四）Weyl半金属。

In recent years, it has become clear that in addition to symmetry, topology plays a crucial role in classifying the phases of matter. In topological phases, defects are frequently associated with interesting and important physics. In the present project we propose to study the interplay of topological phases and magnetic impurities. We will focus on the following contexts: (I) helical edge states of systems in the quantum spin-Hall effect, (ii) topological superconductors supporting Majorana fermions, (iii) Shiba bound states in superconductors, (iv) Weyl semimetals.
