Understanding Non-Split 2-Group Symmetry: (3+1)D SymTFT, Anomaly and Bordism
Zhenbang Gu, Ran Luo, Yi-Nan Wang +1
We present a systematic study of finite, non-split 2-group symmetries with a non-trivial Postnikov class, focusing on the simplest example with a 0-form symmetry and…
On Quantum Aspects of 1-Form Symmetries I: BV-BRST Cohomology and Anomaly Polynomials
Weizhen Jia, Yi-Nan Wang, Yi Zhang
We investigate the quantum aspects of gauging continuous 1-form global symmetries. In this paper, we study the BV-BRST quantization of a 2-form gauge field, described geomet…
On Quantum Aspects of 1-Form Symmetries II: Bordism, Invertible Phases, and Anomalies
Weizhen Jia, Yi-Nan Wang, Yi Zhang
We study quantum anomalies associated with 1-form symmetries from the perspective of invertible phases and bordism. We compute the oriented and spin bordism groups of the Ei…
Constraining F-theory Model Building with QCD Axions
Keren Chen, Qinjian Lou, Yi-Nan Wang
In this paper, we investigate axion physics in 4D F-theory MSSM models. We derive the axion coupling term with QCD gauge fields and the axion potential from a top-down perspective,…
Categorical Symmetries via Operator Algebras
Qiang Jia, Ran Luo, Jiahua Tian +2
We propose that the symmetry category associated to a 2D quantum field theory with 0-form -symmetry with 't Hooft anomaly for a large class of Lie grou…
Higgs Branch and VOA of 4d SCFTs from IIB
Yi-Nan Wang, Wenbin Yan, Peihe Yang
We study the Higgs branch and associated vertex operator algebra (VOA) of 4d superconformal field theories (SCFTs) from the geometric engineering of IIB superstring…
