Generalized global symmetries and holography [PDF]

SciPost Physics, 2018
We study the holographic duals of four-dimensional field theories with 1-form global symmetries, both discrete and continuous. Such higher-form global symmetries are associated with antisymmetric tensor gauge fields in the bulk.

Dark matter and global symmetries

Physics Letters B, 2016
General considerations in general relativity and quantum mechanics are known to potentially rule out continuous global symmetries in the context of any consistent theory of quantum gravity.

Global symmetries of quantum lattice models under non-invertible dualities

SciPost Physics Core
Non-invertible dualities/symmetries have become an important tool in the study of quantum field theories and quantum lattice models in recent years. One of the most studied examples is non-invertible dualities obtained by gauging a discrete group.

Mixed anomalies, two-groups, non-invertible symmetries, and 3d superconformal indices

Journal of High Energy Physics, 2023
Mixed anomalies, higher form symmetries, two-group symmetries and non-invertible symmetries have proved to be useful in providing non-trivial constraints on the dynamics of quantum field theories.

Discrete and higher-form symmetries in SCFTs from wrapped M5-branes

Journal of High Energy Physics, 2021
We analyze topological mass terms of BF type arising in supersymmetric M-theory compactifications to AdS 5. These describe spontaneously broken higher-form gauge symmetries in the bulk. Different choices of boundary conditions for the BF terms yield dual

Non-invertible duality interfaces in field theories with exotic symmetries

Journal of High Energy Physics
In recent years, the concept of global symmetry has generalized considerably. Two dramatic examples of this generalization are the exotic symmetries that govern theories with fractons and non-invertible symmetries, which do not fuse according to a group ...

Global symmetry-breaking and generalized theta-terms in Type IIB EFTs

Journal of High Energy Physics, 2023
A longstanding conjecture states that global symmetries should be absent in quantum gravity. By investigating large classes of Type IIB four-dimensional N $$ \mathcal{N} $$ = 2 effective field theories, we enlist the potential generalized global ...

Higher structure of non-invertible symmetries from Lagrangian descriptions

Journal of High Energy Physics
The symmetry structure of a quantum field theory is determined not only by the topological defects that implement the symmetry and their fusion rules, but also by the topological networks they can form, which is referred to as the higher structure of the

Generalized symmetry breaking scales and weak gravity conjectures

Journal of High Energy Physics, 2022
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 gravity conjecture, the distance conjecture, and the magnetic and axion ...

Analytic bootstrap for the localized magnetic field

Journal of High Energy Physics, 2023
We study the two-point function of local operators in the critical O(N) model in the presence of a magnetic field localized on a line. We use a recently developed conformal dispersion relation to compute the correlator at first order in the ϵ-expansion ...
