关于8个Majorana费米子的注记

Notes on 8 Majorana Fermions

David Tong, Carl Turner

摘要:

八个马约拉纳费米子在$d=1+1$维享有一个triality,置换表示的$SO(8)$全球对称性,费米子变换。这种三重性在超弦的量子化、相互作用拓扑绝缘体的分析以及相关的对称质量产生现象中起着重要的作用。这些笔记的目的是提供一个triality及其应用的介绍,与各种${\bf Z}_2$全球和规范对称性和他们的耦合背景自旋结构的密切关注。

英文摘要:

Eight Majorana fermions in $d=1+1$ dimensions enjoy a triality that permutes the representation of the $SO(8)$ global symmetry in which the fermions transform. This triality plays an important role in the quantization of the superstring, and in the analysis of interacting topological insulators and the associated phenomenon of symmetric mass generation. The purpose of these notes is to provide an introduction to the triality and its applications, with careful attention paid to various ${\bf Z}_2$ global and gauge symmetries and their coupling to background spin structures.
