Chern-Weil global symmetries and how quantum gravity avoids them
Journal of High Energy Physics, 2021 We draw attention to a class of generalized global symmetries, which we call “Chern-Weil global symmetries,” that arise ubiquitously in gauge theories. The Noether currents of these Chern-Weil global symmetries are given by wedge products of gauge field ...

On 2-group global symmetries and their anomalies [PDF]
Journal of High Energy Physics, 2019 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 detail using the language of symmetry defects. We exhibit a simple procedure to

Global Symmetries, Local Symmetries and Groupoids [PDF]
Symmetry, 2021 International audienceLocal symmetries are primarily defined in the case of spacetime, but several authors have defined them outside this context, sometimes with the help of groupoids.

Global symmetries and partial confinement [PDF]
Journal of High Energy Physics, 2022 In gauge theories, spontaneous breaking of the centre symmetry provides a precise definition of deconfinement. In large-N gauge theories, evidence has emerged recently that between confined and deconfined phases a partially-deconfined phase can appear ...

Exploring 2-group global symmetries
Journal of High Energy Physics, 2019 We analyze four-dimensional quantum field theories with continuous 2-group global symmetries. At the level of their charges, such symmetries are identical to a product of continuous flavor or spacetime symmetries with a 1-form global symmetry U(1) B (1) ,

Comments on global symmetries, anomalies, and duality in (2 + 1)d
Journal of High Energy Physics, 2017 We analyze in detail the global symmetries of various (2 + 1)d quantum field theories and couple them to classical background gauge fields. A proper identification of the global symmetries allows us to consider all non-trivial bundles of those background

Constraints on discrete global symmetries in quantum gravity
Journal of High Energy Physics, 2021 The question whether global symmetries can be realized in quantum-gravity-matter-systems has far-reaching phenomenological consequences. Here, we collect evidence that within an asymptotically safe context, discrete global symmetries of the form ℤ n , n >

Quantum groups as global symmetries
Journal of High Energy PhysicsWe study quantum field theories which have quantum groups as global internal symmetries. We show that in such theories operators are generically non-local, and should be thought as living at the ends of topological lines.

Bootstrapping 3D fermions with global symmetries
Journal of High Energy Physics, 2018 We study the conformal bootstrap for 4-point functions of fermions 〈ψ i ψ j ψ k ψ ℓ 〉 in parity-preserving 3d CFTs, where ψ i transforms as a vector under an O(N ) global symmetry.

Classifying global symmetries of 6D SCFTs [PDF]
Journal of High Energy Physics, 2018 We characterize the global symmetries for the conjecturally complete collection of all six dimensional superconformal field theories (6D SCFTs) which are realizable in F-theory and have no frozen singularities.
