Resonant JPZ algebras and 3D Chern--Simons gravity
Remigiusz Durka, Nelson Merino, D. M. Peñafiel
In this work we construct three-dimensional Chern--Simons gravity theories for the six resonant algebras generated by the Lorentz generators , translations , and an…
Conformal renormalization of scalar-tensor theories
Giorgos Anastasiou, Ignacio J. Araya, Mairym Busnego-Barrientos +2
We study a conformally coupled scalar-tensor theory with a quartic potential possessing local conformal symmetry up to a boundary term. We show that requiring the restoration of th…
Most general theory of 3d gravity: Covariant phase space, dual diffeomorphisms, and more
Marc Geiller, Christophe Goeller, Nelson Merino
We show that the phase space of three-dimensional gravity contains two layers of dualities: between diffeomorphisms and a notion of "dual diffeomorphisms" on the one hand, and betw…
Semi-simple enlargement of the algebra from a Chern-Simons theory
Patrick Concha, Nelson Merino, Evelyn Rodríguez +2
In this work we present a BMS-like ansatz for a Chern-Simons theory based on the semi-simple enlargement of the Poincaré symmetry, also known as AdS-Lorentz algebra. We start by sh…
Asymptotic symmetries of three-dimensional Chern-Simons gravity for the Maxwell algebra
Patrick Concha, Nelson Merino, Olivera Miskovic +3
We study a three-dimensional Chern-Simons gravity theory based on the Maxwell algebra. We find that the boundary dynamics is described by an enlargement and deformation of the $\ma…
Pure Lovelock gravity and Chern-Simons theory
P. K. Concha, R. Durka, C. Inostroza +2
We explore the possibility of finding Pure Lovelock gravity as a particular limit of a Chern-Simons action for a specific expansion of the AdS algebra in odd dimensions. We derive…
Dynamical structure of Pure Lovelock gravity
Naresh Dadhich, Remigiusz Durka, Nelson Merino +1
We study dynamical structure of Pure Lovelock gravity in spacetime dimensions higher than four using the Hamiltonian formalism. The action consists of cosmological constant and a s…
Black hole solutions in Chern-Simons AdS supergravity
Gaston Giribet, Nelson Merino, Olivera Miskovic +1
We study charged AdS black hole solutions in five-dimensional Chern-Simons supergravity. The minimal supergroup containing such AdSxU(1) configurations is the superunitary group SU…
Generating Higher-Order Lie Algebras by Expanding Maurer Cartan Forms
Ricardo Caroca, Nelson Merino, Alfredo Pérez +1
By means of a generalization of the Maurer-Cartan expansion method we construct a procedure to obtain expanded higher-order Lie algebras. The expanded higher order Maurer-Cartan eq…
Even-dimensional topological gravity from Chern-Simons gravity
Nelson Merino, Alfredo Perez, Patricio Salgado
It is shown that the topological action for gravity in 2n-dimensions can be obtained from the 2n+1-dimensional Chern-Simons gravity genuinely invariant under the Poincare group. Th…
