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…
Three-dimensional Hypergravity Theories and Semigroup Expansion Method
Ricardo Caroca, Patrick Concha, Javier Matulich +2
In this work we present novel and known three-dimensional hypergravity theories which are obtained by applying the powerful semigroup expansion method. We show that the expansion p…
Non-relativistic and Ultra-relativistic Expansions of Three-dimensional Spin-3 Gravity Theories
Patrick Concha, Carla Henríquez-Báez, Evelyn Rodríguez
In this paper, we present novel and known non-relativistic and ultra-relativistic spin-3 algebras, by considering the Lie algebra expansion method. We start by applying the expansi…
Three-dimensional non-relativistic supergravity and torsion
Patrick Concha, Lucrezia Ravera, Evelyn Rodríguez
In this paper we present a torsional non-relativistic Chern-Simons teleparallel (super)gravity theory in three spacetime dimensions. We start by developing the non-relativistic lim…
On the Supersymmetric Extension of Gauss-Bonnet like Gravity
P. K. Concha, M. C. Ipinza, L. Ravera +1
We explore the supersymmetry invariance of a supergravity theory in the presence of a non-trivial boundary. The explicit construction of a bulk Lagrangian based on an enlarged supe…
N=1 Supergravity and Maxwell superalgebras
P. K. Concha, E. K. Rodríguez
We present the construction of the supergravity action from the minimal Maxwell superalgebra , which can be derived from the $\mathfrak{osp}\left( 4|1\right…
