Title:
Symmetry TFT for non-invertible duality defects

Speaker:
Yunqin Zheng

Abstract:
Symmetry TFT (SymTFT) is a useful tool to decouple the universal data including global symmetries and their ’t Hooft anomalies from the dynamics of quantum field theories. In this talk, we will discuss the SymTFT for the recently widely studied non-invertible duality symmetries in both (1+1)d and (3+1)d. In particular, we will explain how the non-invertible fusion rules can be reproduced from the SymTFT, and will also comment on how one can use SymTFT to distinguish the intrinsically non-invertible symmetry from non-intrinsically non-invertible symmetry.
