Enlarged NH symmetries: Particle Dynamics and Gauge Symmetries
Joaquim Gomis, Jerzy Lukierski
We show how the Newton-Hooke (NH) symmetries, representing a nonrelativistic version of de-Sitter symmetries, can be enlarged by a pair of translation vectors describing in Galilea…
Anisotropic harmonic oscillator, non-commutative Landau problem and exotic Newton-Hooke symmetry
Pedro D. Alvarez, Joaquim Gomis, Kiyoshi Kamimura +1
We investigate the planar anisotropic harmonic oscillator with explicit rotational symmetry as a particle model with non-commutative coordinates. It includes the exotic Newton-Hook…
Kac-Moody Spectrum of (Half-)Maximal Supergravities
Eric Bergshoeff, Joaquim Gomis, Teake Nutma +1
We establish the correspondence between, on one side, the possible gaugings and massive deformations of half-maximal supergravity coupled to vector multiplets and, on the other sid…
Exotic Non-relativistic String
Roberto Casalbuoni, Joaquim Gomis, Giorgio Longhi
We construct a classical non-relativistic string model in 3+1 dimensions. The model contains a spurion tensor field that is responsible for the non-commutative structure of the mod…
General Very Special Relativity is Finsler Geometry
G. W. Gibbons, Joaquim Gomis, C. N. Pope
We ask whether Cohen and Glashow's Very Special Relativity model for Lorentz violation might be modified, perhaps by quantum corrections, possibly producing a curved spacetime with…
