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

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.

Fermionic higher-form symmetries
SciPost Physics, 2023 In this paper, we explore a new type of global symmetries - the fermionic higher-form symmetries. They are generated by topological operators with fermionic parameter, which act on fermionic extended objects.

Generalized symmetries and Noether’s theorem in QFT
Journal of High Energy Physics, 2022 We show that generalized symmetries cannot be charged under a continuous global symmetry having a Noether current. Further, only non-compact generalized symmetries can be charged under a continuous global symmetry.

Continuous generalized symmetries in three dimensions
Journal of High Energy Physics, 2023 We present a class of three-dimensional quantum field theories whose ordinary global symmetries mix with higher-form symmetries to form a continuous 2-group.

Carroll/fracton particles and their correspondence
Journal of High Energy Physics, 2023 We exploit the close relationship between the Carroll and fracton/dipole algebras, together with the method of coadjoint orbits, to define and classify classical Carroll and fracton particles.

Quantum Carroll/fracton particles
Journal of High Energy Physics, 2023 We classify and relate unitary irreducible representations (UIRs) of the Carroll and dipole groups, i.e., we define elementary quantum Carroll and fracton particles and establish a correspondence between them.

Emerging internal symmetries from effective spacetimes
Physics Letters B, 2017 Can global internal and spacetime symmetries be connected without supersymmetry? To answer this question, we investigate Minkowski spacetimes with d space-like extra dimensions and point out under which general conditions external symmetries induce ...

Colourful Poincaré symmetry, gravity and particle actions
Journal of High Energy Physics, 2021 We construct a generalisation of the three-dimensional Poincaré algebra that also includes a colour symmetry factor. This algebra can be used to define coloured Poincaré gravity in three space-time dimensions as well as to study generalisations of ...

Actions and symmetries of NSR superstrings and D-strings [PDF]
, 2000 We present all NSR superstring and super-D-string actions invariant under a set of prescribed gauge transformations, and characterize completely their global symmetries.
