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…

Quantum Duality in Electromagnetism and the Fine-Structure Constant

Clay Cordova, Kantaro Ohmori

We describe the interplay between electric-magnetic duality and higher symmetry in Maxwell theory. When the fine-structure constant is rational, the theory admits non-invertible sy…

Obstructions to Gapped Phases from Non-Invertible Symmetries

Anuj Apte, Clay Cordova, Ho Tat Lam

Quantum systems in 3+1-dimensions that are invariant under gauging a one-form symmetry enjoy novel non-invertible duality symmetries encoded by topological defects. These symmetrie…

Higher Flavor Symmetries in the Standard Model

Clay Cordova, Seth Koren

We initiate the study of the generalized global flavor symmetries of the Standard Model. The presence of nonzero triangle diagrams between the flavor currents and the $U(1…

Geometry of Conformal Manifolds and the Inversion Formula

Bruno Balthazar, Clay Cordova

Families of conformal field theories are naturally endowed with a Riemannian geometry which is locally encoded by correlation functions of exactly marginal operators. We show that…

Neutrino Masses from Generalized Symmetry Breaking

Clay Cordova, Sungwoo Hong, Seth Koren +1

We explore generalized global symmetries in theories of physics beyond the Standard Model. Theories of bosons generically contain 'non-invertible' chiral symmetries, whose pre…

Symmetry Enriched -Theorems & SPT Transitions

Clay Cordova, Diego García-Sepúlveda

We derive universal constraints on rational conformal field theories (CFTs) that can arise as transitions between topological theories protected by a global symmetry. The…

Line Defect Quantum Numbers & Anomalies

T. Daniel Brennan, Clay Cordova, Thomas T. Dumitrescu

We explore the connection between the global symmetry quantum numbers of line defects and 't Hooft anomalies. Relative to local (point) operators, line defects may transform projec…

Snowmass White Paper: Generalized Symmetries in Quantum Field Theory and Beyond

Clay Cordova, Thomas T. Dumitrescu, Kenneth Intriligator +1

Symmetry plays a central role in quantum field theory. Recent developments include symmetries that act on defects and other subsystems, and symmetries that are categorical rather t…

Non-Invertible Chiral Symmetry and Exponential Hierarchies

Clay Cordova, Kantaro Ohmori

We elucidate the fate of classical symmetries which suffer from abelian Adler-Bell-Jackiw anomalies. Instead of being completely destroyed, these symmetries survive as non-invertib…

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…

Generalized Symmetry Breaking Scales and Weak Gravity Conjectures

Clay Cordova, Kantaro Ohmori, Tom Rudelius

We explore the notion of approximate global symmetries in quantum field theory and quantum gravity. We show that a variety of conjectures about quantum gravity, including the weak…

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…

Calabi-Yau CFTs and Random Matrices

Nima Afkhami-Jeddi, Anthony Ashmore, Clay Cordova

Using numerical methods for finding Ricci-flat metrics, we explore the spectrum of local operators in two-dimensional conformal field theories defined by sigma models on Calabi-Yau…

Axions, Higher-Groups, and Emergent Symmetry

T. Daniel Brennan, Clay Cordova

Axions, periodic scalar fields coupled to gauge fields through the instanton density, have a rich variety of higher-form global symmetries. These include a two-form global symmetry…

2-Group Global Symmetries and Anomalies in Six-Dimensional Quantum Field Theories

Clay Cordova, Thomas T. Dumitrescu, Kenneth Intriligator

We examine six-dimensional quantum field theories through the lens of higher-form global symmetries. Every Yang-Mills gauge theory in six dimensions, with field strength ,…

Clay Cordova, Thomas T. Dumitrescu, Kenneth Intriligator

We consider conformal and 't Hooft anomalies in six-dimensional superconformal field theories, focusing on those conformal anomalies that determine the two- and th…

Anomaly Constraints on Gapped Phases with Discrete Chiral Symmetry

Clay Cordova, Kantaro Ohmori

We prove that in quantum field theories with symmetry, certain anomalies forbid a symmetry-preserving vacuum state with a gapped spectrum. In particular, th…
