四维$\mathbb{Z}_2$纯格点规范理论中的不可逆拓扑缺陷

Non-invertible topological defects in 4-dimensional $\mathbb{Z}_2$ pure lattice gauge theory

Masataka Koide, Yuta Nagoya, Satoshi Yamaguchi

摘要:

我们探讨了四维纯$\mathbb{Z}_2$格点规范理论中的拓扑缺陷。该理论具有1-形式的$\mathbb{Z}_{2}$中心对称性和Kramers-Wannier-Wegner(KWW)对偶性。我们构造KWW对偶拓扑亏损的方法类似于Aasen,Mong,Fendley arXiv:1601.07185对二维伊辛模型构造的方法.这些对偶缺陷原来是不可逆的。我们还构造了1型$\mathbb{Z}_{2}$对称缺陷以及KWW对偶缺陷和1型$\mathbb{Z}_{2}$中心对称缺陷之间的连接。导出了这些缺陷之间的交叉关系。利用这些交叉关系计算了这些拓扑缺陷的某些组态的期望值。

英文摘要:

We explore topological defects in the 4-dimensional pure $\mathbb{Z}_2$ lattice gauge theory. This theory has 1-form $\mathbb{Z}_{2}$ center symmetry as well as the Kramers-Wannier-Wegner (KWW) duality. We construct the KWW duality topological defects in the similar way to that constructed by Aasen, Mong, Fendley arXiv:1601.07185 for the 2-dimensional Ising model. These duality defects turn out to be non-invertible. We also construct the 1-form $\mathbb{Z}_{2}$ symmetry defects as well as the junctions among KWW duality defects and 1-form $\mathbb{Z}_{2}$ center symmetry defects. The crossing relations among these defects are derived. The expectation values of some configurations of these topological defects are calculated by using these crossing relations.
