与角态有关的拓扑不变量的分类
Classification of topological invariants related to corner states
摘要：
本文讨论了角点晶格上的体表面带隙哈密顿算符，并提出了一个角点态拓扑不变量周期表，用于高阶拓扑绝缘体的研究.我们的表是基于四件事：（1）拓扑不变量的定义，（2）证明它们与角态的关系，（3）K-群的计算和（4）明确的例子的建设。
英文摘要：
We discuss some bulk-surfaces gapped Hamiltonians on a lattice with corners and propose a periodic table for topological invariants related to corner states aimed at studies of higher-order topological insulators. Our table is based on four things: (1) the definition of topological invariants, (2) a proof of their relation with corner states (3) computations of K-groups and (4) a construction of explicit examples.
