SymTFT Entanglement and Holographic (Non)-Factorization
Ethan Torres, Xingyang Yu
Given two otherwise decoupled -dimensional CFTs which possess a common (finite) symmetry subcategory, one can consider entangled boundary states of their -dimensional Sym…
On mixed 't Hooft anomalies of emergent symmetries
Wei Gu, Du Pei, Xingyang Yu
In this paper, we investigate the dynamical constraints imposed on the UV theory when it develops an emergent symmetry in the infrared with mixed 't Hooft anomalies. We demonstrate…
Gauging in Parameter Space: A Top-Down Perspective
Xingyang Yu
In this paper, we discuss a novel top-down perspective on gauging parameters in quantum field theories (QFTs) by promoting them to partially dynamical fields. Through a generalized…
Generalized Symmetries in 2D from String Theory: SymTFTs, Intrinsic Relativeness, and Anomalies of Non-invertible Symmetries
Sebastian Franco, Xingyang Yu
Generalized global symmetries, in particular non-invertible and categorical symmetries, have become a focal point in the recent study of quantum field theory (QFT). In this paper,…
Non-invertible Symmetries in 2D from Type IIB String Theory
Xingyang Yu
We propose a top-down approach to non-invertible symmetries in 2D QFTs and their associated symmetry topological field theories. We focus on the gauge theory engineered on D1-brane…
SymTrees and Multi-Sector QFTs
Florent Baume, Jonathan J. Heckman, Max Hübner +3
The global symmetries of a -dimensional QFT can, in many cases, be captured in terms of a -dimensional symmetry topological field theory (SymTFT). In this work we constru…
