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

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.

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

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.

Generalized global symmetries of T[M] theories. Part I [PDF]

Journal of High Energy Physics, 2020
We study reductions of 6d theories on a d-dimensional manifold Md, focusing on the interplay between symmetries, anomalies, and dynamics of the resulting (6 −d)-dimensional theory T[Md].

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 ...

Charged eigenstate thermalization, Euclidean wormholes and global symmetries in quantum gravity [PDF]

SciPost Physics, 2020
We generalize the eigenstate thermalization hypothesis to systems with global symmetries. We present two versions, one with microscopic charge conservation and one with exponentially suppressed violations.

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 ...

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.
