On 2-group global symmetries and their anomalies
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

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.

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.

Consequences of symmetry fractionalization without 1-form global symmetries
Journal of High Energy PhysicsA bstract We study the fractionalization of 0-form global symmetries on line operators in theories without 1-form global symmetries. The projective transformation properties of line operators are renormalization group invariant, and we derive constraints which are similar to ...

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.

Duality, Generalized Global Symmetries and Jet Space Isometries
Universe, 2021 We revisit universal features of duality in linear and nonlinear relativistic scalar and Abelian 1-form theories with single or multiple fields, which exhibit ordinary or generalized global symmetries.

Global Symmetries, Local Symmetries and Groupoids [PDF]
Symmetry, 2021 Local symmetries are primarily defined in the case of spacetime, but several authors have defined them outside this context, sometimes with the help of groupoids. We show that, in many cases, local symmetries can be defined as global symmetries. We also show that groups can be used, rather than groupoids, to handle local symmetries.

Disconnected 0-form and 2-group symmetries
Journal of High Energy Physics, 2023 Quantum field theories can have both continuous and finite 0-form symmetries. We study global symmetry structures that arise when both kinds of 0-form symmetries are present. The global structure associated to continuous 0-form symmetries is described by

Proof of the universal density of charged states in QFT
Journal of High Energy Physics, 2021 We prove a recent conjecture by Harlow and Ooguri concerning a universal formula for the charged density of states in QFT at high energies for global symmetries associated with finite groups. An equivalent statement, based on the entropic order parameter
