3D Carrollian gravity from 2D Euclidean symmetry

Patrick Concha, Evelyn Rodríguez, Sebastián Salgado

Carroll symmetry arises from Poincaré symmetry when the speed of light is sent to zero. In this work, we apply the Lie algebra expansion method to find the Carroll versions of diff…

A Conformal Approach to Carroll Gravity

Eric A. Bergshoeff, Patrick Concha, Octavio Fierro +2

We show how to take the first step in the conformal program for constructing general matter couplings to Carroll gravity. In particular, we couple a single massless electric/magnet…

Three-dimensional non-relativistic Hietarinta supergravity

Patrick Concha, Evelyn Rodríguez, Sebastián Salgado

In this work we present the non-relativistic regime of the Hietarinta gravity theory and its extension to supergravity. At the bosonic level, we derive the non-relativistic version…

Four dimensional topological supergravities from transgression field theory

Patrick Concha, Fernando Izaurieta, Evelyn Rodríguez +1

In this work, we propose a four-dimensional gauged Wess-Zumino-Witten model, obtained as a dimensional reduction from a transgression field theory invariant under the $\mathcal{N}=…

Hietarinta Chern-Simons supergravity and its asymptotic structure

Patrick Concha, Octavio Fierro, Evelyn Rodríguez

In this paper we present the Hietarinta Chern-Simons supergravity theory in three space-time dimensions which extends the simplest Poincaré supergravity theory. After approaching t…

Enlarged super- algebra and its flat limit

Javier Matulich, Evelyn Rodríguez

In this paper we analyze the asymptotic symmetries of the three-dimensional Chern-Simons supergravity for a supersymmetric extension of the semi-simple enlargement of the Poincaré…

Extended Kinematical 3D Gravity Theories

Patrick Concha, Daniel Pino, Lucrezia Ravera +1

In this work, we classify all extended and generalized kinematical Lie algebras that can be obtained by expanding the algebra. We show that the Lie…

Non-relativistic limit of the Mielke-Baekler gravity theory

Patrick Concha, Nelson Merino, Evelyn Rodríguez

In this paper, we present the most general non-relativistic Chern-Simons gravity model in three spacetime dimensions. We first study the non-relativistic limit of the Mielke-Baekle…

Inönü-Wigner Contraction and Supergravity

P. K. Concha, O. Fierro, E. K. Rodríguez

We present a generalization of the standard Inönü-Wigner contraction by rescaling not only the generators of a Lie superalgebra but also the arbitrary constants appearing in the co…
