Non-relativistic and ultra-relativistic scaling limits of multimetric gravity
A bstract We present a method of contraction that can be applied to re-construct the recent
extended non-relativistic and ultra-relativistic algebras as well as corresponding action …

Non-Lorentzian Supergravity
EA Bergshoeff, J Rosseel - Handbook of quantum gravity, 2023 - Springer
We give an overview of the different non-Lorentzian supergravity theories in diverse
dimensions that have been constructed in recent years. After giving a detailed discussion of …

Nonrelativistic spin-3 symmetries in dimensions from expanded and extended Nappi-Witten algebras
R Caroca, DM Peñafiel, P Salgado-Rebolledo - Physical Review D, 2023 - APS
We show that infinite families of Galilean spin-3 symmetries in 2+ 1 dimensions, which
include higher-spin extensions of the Bargmann, Newton-Hooke, nonrelativistic Maxwell …

Three-dimensional non-relativistic supergravity and torsion
In this paper we present a torsional non-relativi-stic Chern–Simons (super) gravity theory in
three spacetime dimensions. We start by developing the non-relativistic limit of the purely …

Three-dimensional hypergravity theories and semigroup expansion method
A bstract In this work, we apply the semigroup expansion method of Lie algebras to construct
novel and known three-dimensional hypergravity theories. We show that the expansion …
