ICTP lectures on (non-) invertible generalized symmetries

S Schäfer-Nameki - Physics Reports, 2024 - Elsevier
What comprises a global symmetry of a Quantum Field Theory (QFT) has been vastly
expanded in the past 10 years to include not only symmetries acting on higher-dimensional …

Noninvertible global symmetries in the standard model

Y Choi, HT Lam, SH Shao - Physical Review Letters, 2022 - APS
We identify infinitely many noninvertible generalized global symmetries in QED and QCD for
the real world in the massless limit. In QED, while there is no conserved Noether current for …

Noninvertible chiral symmetry and exponential hierarchies

C Córdova, K Ohmori - Physical Review X, 2023 - APS
We elucidate the fate of classical symmetries which suffer from Abelian Adler-Bell-Jackiw
anomalies. Instead of being completely destroyed, these symmetries survive as …

Higher gauging and non-invertible condensation defects

K Roumpedakis, S Seifnashri, SH Shao - … in Mathematical Physics, 2023 - Springer
We discuss invertible and non-invertible topological condensation defects arising from
gauging a discrete higher-form symmetry on a higher codimensional manifold in spacetime …

Noninvertible duality defects in dimensions

Y Choi, C Cordova, PS Hsin, HT Lam, SH Shao - Physical Review D, 2022 - APS
For any quantum system invariant under gauging a higher-form global symmetry, we
construct a noninvertible topological defect by gauging in only half of the spacetime. This …

Symmetry TFTs and anomalies of non-invertible symmetries

J Kaidi, E Nardoni, G Zafrir, Y Zheng - Journal of High Energy Physics, 2023 - Springer
A bstract It is known that the't Hooft anomalies of invertible global symmetries can be
characterized by an invertible TQFT in one higher dimension. The analogous statement …

Symmetry TFTs for non-invertible defects

J Kaidi, K Ohmori, Y Zheng - Communications in Mathematical Physics, 2023 - Springer
Given any symmetry acting on ad-dimensional quantum field theory, there is an associated
(d+ 1)-dimensional topological field theory known as the Symmetry TFT (SymTFT). The …

Kramers-Wannier-like Duality Defects in Gauge Theories

J Kaidi, K Ohmori, Y Zheng - Physical review letters, 2022 - APS
We introduce a class of noninvertible topological defects in (3+ 1) D gauge theories whose
fusion rules are the higher-dimensional analogs of those of the Kramers-Wannier defect in …

Snowmass white paper: Generalized symmetries in quantum field theory and beyond

C Cordova, TT Dumitrescu, K Intriligator… - arXiv preprint arXiv …, 2022 - arxiv.org
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 …
