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 ...

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.

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.

A particle model with extra dimensions from coadjoint Poincaré symmetry

Journal of High Energy Physics, 2020
Starting from the coadjoint Poincaré algebra we construct a point particle relativistic model with an interpretation in terms of extra-dimensional variables.

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.

Linearized off-shell 4+7 supergeometry of 11D supergravity

Journal of High Energy Physics, 2022
We describe the linearized supergeometry of eleven dimensional supergravity with four off-shell local supersymmetries. We start with a background Minkowski 11D, N=1 superspace, and an additional ingredient of a global, constant, G 2-structure which ...

Asymptotic O $$ \mathcal{O} $$ (r) gauge symmetries and gauge-invariant Poincaré generators in higher spacetime dimensions

Journal of High Energy Physics, 2023
The asymptotic symmetries of electromagnetism in all higher spacetime dimensions d > 4 are extended, by incorporating consistently angle-dependent u(1) gauge transformations with a linear growth in the radial coordinate at spatial infinity. Finiteness of

Symmetries of Bianchi I space–times [PDF]

Journal of Mathematical Physics, 2000
All diagonal proper Bianchi I space–times are determined which admit certain important symmetries. It is shown that for Homothetic motions, Conformal motions and Kinematic Self-Similarities the resulting space–times are defined explicitly in terms of a set of parameters, whereas Affine Collineations, Ricci Collineations, and Curvature Collineations, if

Tensors and spinors in de Sitter space

Journal of High Energy Physics, 2022
We construct the Wightman function for symmetric traceless tensors and Dirac fermions in dS d+1 in a coordinate and index free formalism using a d + 2 dimensional ambient space. We expand the embedding space formalism to cover spinor and tensor fields in
