摘要:

迪克格拉夫-维滕理论在拓扑物质相和广义全局对称性研究中应用广泛。我们开发了一种方法,通过从阿贝尔迪克格拉夫-维滕理论的 BF 拉格朗日量 gauge H^(0) 对称性,来构造非阿贝尔迪克格拉夫-维滕理论的 BF 型拉格朗日量。当 H 非平凡地排列原始理论的操作符时,H-gauged 理论的拉格朗日量通过带有局部系数的上同调构造。我们利用同调论分析拉格朗日量的结构及其 gauge 变换,并通过匹配基本链接不变量构建算子谱并验证拉格朗日量。

英文摘要:

Dijkgraaf-Witten theories have a wide range of applications in topological phases of matter and the study of generalized global symmetries. We develop a method to construct BF-type Lagrangians for Dijkgraaf-Witten theories with non-abelian gauge group by gauging $H^{(0)}$ symmetries from a BF-Lagrangian of an abelian Dijkgraaf-Witten theory. When $H$ nontrivially permutes the operators of the original theory, the Lagrangian of the $H$-gauged theory is constructed with cohomologies with local coefficients. We analyze the structure of the Lagrangians and their gauge transformations with homotopy theory. We also construct the operator spectrum and verify the Lagrangians by matching elementary linking invariants.
