关于condensed matter中拓扑不变量的注记

A note on topological invariants in condensed matter

J. M. Fonseca, V. L. Carvalho-Santos

摘要:

我们讨论了拓扑不变量的一些方面,分类拓扑状态的物质,重点是拓扑绝缘体。解决的主要方面是,如果只有两个拓扑阶段布洛赫哈密顿量是时间反演不变的,或者如果有更多的相位,具有不同的拓扑不变量。从数学的角度来看,可能存在更多的拓扑相的物质作为一个子类的一个完善的阶段。

英文摘要:

We discuss some aspects of topological invariants that classify topological states of matter with emphasis on topological insulators. The main aspect addressed is if there are only two topological phases to Bloch Hamiltonian that are time reversal invariant or if there are more phases that has different topological invariants. From a mathematical point of view may exist more topological phases of matter as a subclass of one well established phase.
