Postcarrollian gravity
Florian Ecker, Daniel Grumiller, Patricio Salgado-Rebolledo
We construct postcarrollian gravity models in two, three, and four spacetime dimensions by applying algebraic expansion methods. As a byproduct, we present the most general postcar…
Hydrostatic equilibrium in multi-Weyl semimetals
Jewel Kumar Ghosh, Francisco Peña-Benítez, Patricio Salgado-Rebolledo
We study the hydrostatic equilibrium of multi-Weyl semimetals, a class of systems with Weyl-like quasi-particles but anisotropic dispersion relation $ω^2 \sim k_\parallel^2 + k_\pe…
Cartan-like formulation of electric Carrollian gravity
Simon Pekar, Alfredo Pérez, Patricio Salgado-Rebolledo
We present a Cartan-like first-order action principle for electric Carrollian gravity. The action is invariant under the local homogeneous Carroll group, albeit in a different repr…
Carroll swiftons
Florian Ecker, Daniel Grumiller, Marc Henneaux +1
We construct Carroll-invariant theories with fields propagating outside the Carroll lightcone, i.e., at a speed strictly greater than zero (`Carroll swiftons'). We first consider m…
Fracton gauge fields from higher-dimensional gravity
Francisco Peña-Benítez, Patricio Salgado-Rebolledo
We show that the fractonic dipole-conserving algebra can be obtained as an Aristotelian (and pseudo-Carrollian) contraction of the Poincaré algebra in one dimension higher. Such co…
Magnetic Carrollian gravity from the Carroll algebra
Andrea Campoleoni, Marc Henneaux, Simon Pekar +2
We explicitly establish the equivalence between the magnetic Carrollian limit of Einstein gravity defined through the Hamiltonian formalism and the Carrollian theory of gravity def…
Carroll contractions of Lorentz-invariant theories
Marc Henneaux, Patricio Salgado-Rebolledo
We consider Carroll-invariant limits of Lorentz-invariant field theories. We show that just as in the case of electromagnetism, there are two inequivalent limits, one "electric" an…
Emerging (2+1)D massive graviton in graphene-like systems
Patricio Salgado-Rebolledo, Jiannis K. Pachos
Unlike the fundamental forces of the Standard Model the quantum effects of gravity are still experimentally inaccessible. Rather surprisingly quantum aspects of gravity, such as ma…
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 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…
Gravitating Meron-like topological solitons in massive Yang-Mills theory and the Einstein-Skyrme model
Marcelo Ipinza, Patricio Salgado-Rebolledo
We show that gravitating Merons in -dimensional massive Yang-Mills theory can be mapped to solutions of the Einstein-Skyrme model. The identification of the solutions relies on…
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…
Newton-Hooke/Carrollian expansions of (A)dS and Chern-Simons gravity
Joaquim Gomis, Axel Kleinschmidt, Jakob Palmkvist +1
We construct finite- and infinite-dimensional non-relativistic extensions of the Newton-Hooke and Carroll (A)dS algebras using the algebra expansion method, starting from the (anti…
Symmetries of post-Galilean expansions
Joaquim Gomis, Axel Kleinschmidt, Jakob Palmkvist +1
In this letter we study an infinite extension of the Galilei symmetry group in any dimension that can be thought of as a non-relativistic or post-Galilean expansion of the Poincare…
Non-relativistic symmetries in three space-time dimensions and the Nappi-Witten algebra
Diego M. Peñafiel, Patricio Salgado-Rebolledo
We show that the Extended Bargmann and Newton-Hooke algebras in 2+1 dimensions can be obtained as expansions of the Nappi-Witten algebra. The result can be generalized to obtain tw…
The Maxwell group in 2+1 dimensions and its infinite-dimensional enhancements
Patricio Salgado-Rebolledo
The Maxwell group in 2+1 dimensions is given by a particular extension of a semi-direct product. This mathematical structure provides a sound framework to study different generaliz…
