Generalized Global Symmetries of Theories: Part II
Sergei Gukov, Po-Shen Hsin, Du Pei
We continue the investigation of symmetries and anomalies of theories obtained by compactifying 6d SCFTs on an internal manifold . We extend the notion of "polarizations…
Detecting Standard Model Gauge Group from Generalized Fractional Quantum Hall Effect
Po-Shen Hsin, Jaume Gomis
The Standard Model of particle physics stands as one of the most profound and successful frameworks for describing the fundamental workings of nature. The global form of the Standa…
Time-Reversal Anomalies of QCD and QED
Po-Shen Hsin
Anomalies of global symmetry provide powerful tool to constrain the dynamics of quantum systems, such as anomaly matching in the renormalization group flow and obstruction to symme…
Anomalies of Non-Invertible Symmetries in (3+1)d
Clay Cordova, Po-Shen Hsin, Carolyn Zhang
Anomalies of global symmetries are important tools for understanding the dynamics of quantum systems. We investigate anomalies of non-invertible symmetries in 3+1d using 4+1d bulk…
Anomalies and Symmetry Fractionalization
Diego Delmastro, Jaume Gomis, Po-Shen Hsin +1
We study ordinary, zero-form symmetry and its anomalies in a system with a one-form symmetry . In a theory with one-form symmetry, the action of on charged line operator…
Non-invertible Condensation, Duality, and Triality Defects in 3+1 Dimensions
Yichul Choi, Clay Cordova, Po-Shen Hsin +2
We discuss a variety of codimension-one, non-invertible topological defects in general 3+1d QFTs with a discrete one-form global symmetry. These include condensation defects from h…
Non-Invertible Duality Defects in 3+1 Dimensions
Yichul Choi, Clay Cordova, Po-Shen Hsin +2
For any quantum system invariant under gauging a higher-form global symmetry, we construct a non-invertible topological defect by gauging in only half of spacetime. This generalize…
A violation of global symmetries from replica wormholes and the fate of black hole remnants
Po-Shen Hsin, Luca V. Iliesiu, Zhenbin Yang
We show that the presence of replica wormholes in the Euclidean path integral of gravity leads to a non-perturbative violation of charge conservation for any global symmetry presen…
Generalized Global Symmetries of Theories. I
Sergei Gukov, Po-Shen Hsin, Du Pei
We study reductions of 6d theories on a -dimensional manifold , focusing on the interplay between symmetries, anomalies, and dynamics of the resulting -dimensional t…
Discrete Theta Angles, Symmetries and Anomalies
Po-Shen Hsin, Ho Tat Lam
Gauge theories in various dimensions often admit discrete theta angles, that arise from gauging a global symmetry with an additional symmetry protected topological (SPT) phase. We…
Rozansky-Witten geometry of Coulomb branches and logarithmic knot invariants
Sergei Gukov, Po-Shen Hsin, Hiraku Nakajima +3
By studying Rozansky-Witten theory with non-compact target spaces we find new connections with knot invariants whose physical interpretation was not known. This opens up several ne…
Comments on One-Form Global Symmetries and Their Gauging in 3d and 4d
Po-Shen Hsin, Ho Tat Lam, Nathan Seiberg
We study 3d and 4d systems with a one-form global symmetry, explore their consequences, and analyze their gauging. For simplicity, we focus on one-form symmetries. A…
Exceptional Chern-Simons-Matter Dualities
Clay Cordova, Po-Shen Hsin, Kantaro Ohmori
We use conformal embeddings involving exceptional affine Kac-Moody algebras to derive new dualities of three-dimensional topological field theories. These generalize the familiar l…
On 2-Group Global Symmetries and Their Anomalies
Francesco Benini, Clay Cordova, Po-Shen Hsin
In general quantum field theories (QFTs), ordinary (0-form) global symmetries and 1-form symmetries can combine into 2-group global symmetries. We describe this phenomenon in detai…
Global Symmetries, Counterterms, and Duality in Chern-Simons Matter Theories with Orthogonal Gauge Groups
Clay Cordova, Po-Shen Hsin, Nathan Seiberg
We study three-dimensional gauge theories based on orthogonal groups. Depending on the global form of the group these theories admit discrete -parameters, which control the weig…
Level/rank Duality and Chern-Simons-Matter Theories
Po-Shen Hsin, Nathan Seiberg
We discuss in detail level/rank duality in three-dimensional Chern-Simons theories and various related dualities in three-dimensional Chern-Simons-matter theories. We couple the du…
Anomalies, Conformal Manifolds, and Spheres
Jaume Gomis, Po-Shen Hsin, Zohar Komargodski +3
The two-point function of exactly marginal operators leads to a universal contribution to the trace anomaly in even dimensions. We study aspects of this trace anomaly, emphasizing…

Heng-Yu Chen, Po-Shen Hsin, Peter Koroteev
We continue to investigate the relationship between the infrared physics of N=2 supersymmetric gauge theories in four dimensions and various integrable models such as Gaudin, Calog…
