Anomaly of Continuous Symmetries from Topological Defect Network

Qiang Jia, Ran Luo, Jiahua Tian +2

We show that the 't Hooft anomaly of a quantum field theory with continuous flavor symmetry can be detected from rearrangements of the topological defect webs implementing the glob…

Categorical Continuous Symmetry

Qiang Jia, Ran Luo, Jiahua Tian +2

We define the symmetry category in 1+1d for continuous 0-form $G$ -symmetry to be $Sky^{τ} (G)$ , the category of skyscraper sheaves of finite dimensional vector spaces with fi…

Symmetry, Symmetry Topological Field Theory and von Neumann Algebra

Qiang Jia, Jiahua Tian

We study the additivity and Haag duality of the von Neumann algebra of a quantum field theory $T_{F}$ with 0-form (and the dual $(d - 2)$ -form) (non)-invertible glo…
