本文研究了二维和三维拓扑晶体绝缘体在时间反转和反射光保护下的相互作用效应。通过对玻色化边缘态的稳定性分析，我们发现，由对称性保护的二维保序拓扑相的分类由相互作用从到减少，其中对称性表示其镜像平面是二维平面本身的反射。通过扩展Isobe和Fu最近提出的方法，我们表明三维SPT相的分类（即，拓扑晶体绝缘体）的对称性保护减少到相互作用。
We study interaction effects on the topological crystalline insulators protected by time-reversaland reflection symmetryin two and three spatial dimensions. From the stability analysis of the edge states with bosonization, we find that the classification of the two-dimensional symmetry-protected topological (SPT) phases protected bysymmetry is reduced fromtoby interactions where thesymmetry denotes the reflection whose mirror plane is the two-dimensional plane itself. By extending the approach recently proposed by Isobe and Fu, we show that the classification of the three-dimensional SPT phases (i.e., topological crystalline insulators) protected bysymmetry is reduced fromtoby interactions.
