Non-relativistic and Carrollian limits of Jackiw-Teitelboim gravity
Joaquim Gomis, Diego Hidalgo, Patricio Salgado-Rebolledo
We construct the non-relativistic and Carrollian versions of Jackiw-Teitelboim gravity. In the second order formulation, there are no divergences in the non-relativistic and Carrol…
A canonical realization of the Weyl BMS symmetry
Carles Batlle, Víctor Campello, Joaquim Gomis
We construct a free field realization of an extension of the BMS algebra in dimensional space-time. Besides the supertranslations and superrotations, the extension contains a…
A particle model with extra dimensions from Coadjoint Poincare' Symmetry
Andrea Barducci, Roberto Casalbuoni, Joaquim Gomis
Starting from the coadjoint Poincaré algebra we construct a point particle relativistic model with an interpretation in terms of extra-dimensional variables. The starting coadjoint…
A free Lie algebra approach to curvature corrections to flat space-time
Joaquim Gomis, Axel Kleinschmidt, Diederik Roest +1
We investigate a systematic approach to include curvature corrections to the isometry algebra of flat space-time order-by-order in the curvature scale. The Poincaré algebra is exte…
Space-time Schrödinger symmetries of a post-Galilean particle
Carles Batlle, Joaquim Gomis
We study the space-time symmetries of the actions obtained by expanding the action for a massive free relativistic particle around the Galilean action. We obtain all the point spac…
Non-relativistic limits and three-dimensional coadjoint Poincare gravity
Eric Bergshoeff, Joaquim Gomis, Patricio Salgado-Rebolledo
We show that a recently proposed action for three-dimensional non-relativistic gravity can be obtained by taking the limit of a relativistic Lagrangian that involves the co-adjoint…
