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.

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 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.

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.

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 ...

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.

Sterile neutrinos and global symmetries [PDF]
Physical Review D, 2005 We use an effective-field-theory approach to construct models with naturally light sterile neutrinos, due to either exact or accidental global symmetries. The most attractive models we find are based on gauge symmetries, either discrete or continuous. We give examples of simple models based on Z_N, U(1)', and SU(2)'.

Duality and global symmetries [PDF]
Nuclear Physics B - Proceedings Supplements, 1998 This is a general introduction to duality in field theories. The existence and breaking of global symmetries is used as a guideline to systematically prove duality between different field theories. Systems discussed include abelian and non-abelian T-duality in string theory, abelian and nonabelian bosonization, and duality for massless and massive ...

Dyson’s classification and real division superalgebras
Journal of High Energy Physics, 2021 It is well-known that unitary irreducible representations of groups can be usefully classified in a 3-fold classification scheme: Real, Complex, Quaternionic.

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 ...
