condensed matter有效理论中拓扑项的简短指南

A short guide to topological terms in the effective theories of condensed matter

Akihiro Tanaka, Shintaro Takayoshi

摘要:

这篇文章的意思是作为一个温和的介绍“拓扑术语”,往往发挥了决定性的作用,在有效的理论描述拓扑量子效应在凝聚态系统。我们首先举几个突出的例子,主要来自量子磁学和超流体/超导体领域。然后,我们简要地讨论了这些想法是如何找到体现在研究的拓扑相,这是在某种意义上的推广拓扑绝缘体的概念,以更广泛的材料,包括磁铁和冷原子。

英文摘要:

This article is meant as a gentle introduction to the "topological terms" that often play a decisive role in effective theories describing topological quantum effects in condensed matter systems. We first take up several prominent examples, mainly from the area of quantum magnetism and superfluids/superconductors. We then briefly discuss how these ideas are now finding incarnations in the studies of symmetry-protected topological phases, which are in a sense the generalization of the concept of topological insulators to a wider range of materials, including magnets and cold atoms.
