Space-time Schrödinger symmetries of a post-Galilean particle
Journal of High Energy Physics, 2020 We study the space-time symmetries of the actions obtained by expanding the action for a massive free relativistic particle around the Galilean action [1]. We obtain all the point space-time symmetries of the post-Galilean actions by working in canonical

Tunable transport with broken space–time symmetries [PDF]
Physics Reports, 2014 Transport properties of particles and waves in spatially periodic structures that are driven by external time-dependent forces manifestly depend on the space-time symmetries of the corresponding equations of motion. A systematic analysis of these symmetries uncovers the conditions necessary for obtaining directed transport.

Phonon-induced Floquet topological phases protected by space-time symmetries
Physical Review Research, 2020 For systems with spatial and nonspatial symmetries, the topological classification depends not only on these symmetries but also on the commutation/anticommutation relations between spatial and nonspatial symmetries.

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.

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.

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 ...

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 ...
