论文摘要
关于高$ T_C $超导体的研究通常并不集中于对这些材料中电子带的拓扑结构的分析。在本文中,我们整理并讨论了一些众所周知的实验可观察到的,表明可能存在某些拓扑的特征。实验建议的拓扑特征包括尺寸还原,通过环统计确定的电子传输,绕组数,Weyl Fermions等。我们建议,拓扑比乐队拓扑更广泛,可能是高$ T_C $超导性机制的关键。
Research on high-$T_c$ superconductors has generally not focused on analysis of the topological structure of electronic bands in these materials. In this article we collate and discuss several well-known experimental observables that signal that certain signatures of topology may be present. The topological signatures suggested by experiment include dimensional reduction, electronic transport determined by loop statistics, a winding number, Weyl fermions, and others. We suggest that topology, in a wider sense than band topology, may be key to the mechanism of high-$T_c$ superconductivity.
