Hamiltonian analysis of an Effective action coupled to the Palatini action in 4 dimensions
Ricardo Escobedo, Roberto Santos-Silva, Claudia Moreno +1
We carry out the canonical analysis of the coupling of a -dimensional effective action that arises from a dimensional reduction of a -dimensional BF theory to the Palatini ac…
Towards a de Sitter quintom-like cosmology from a reduction of a 7-dimensional theory
Ricardo Escobedo, Roberto Santos-Silva, Claudia Moreno +1
In this article, we analyze a 7-dimensional theory that, upon dimensional reduction, transforms into an effective 4-dimensional action in which a generic metric is involved. A…
Post-Newtonian Gravitational Waves with cosmological constant from the Einstein-Hilbert theory
Ricardo Escobedo, Claudia Moreno, Rafael Hernández-Jiménez
We study the Post-Newtonian approach implemented to the Einstein-Hilbert action adding the cosmological constant at 1PN order. We consider very small values of to derive th…
Fermions coupled to the Palatini action in dimensions
Jorge Romero, Merced Montesinos, Ricardo Escobedo
We study minimal and nonminimal couplings of fermions to the Palatini action in dimensions () from the Lagrangian and Hamiltonian viewpoints. The Lagrangian action con…
Straightforward Hamiltonian analysis of gravity in dimensions
Merced Montesinos, Ricardo Escobedo, Mariano Celada
We perform, in a manifestly [] covariant fashion, the Hamiltonian analysis of general relativity in dimensions written as a constrained theory. We solve…
Canonical analysis of gravity in dimensions
Mariano Celada, Ricardo Escobedo, Merced Montesinos
In this paper we perform in a manifestly [or, alternatively ] covariant fashion, the canonical analysis of general relativity in dimensions written as a cons…
Canonical analysis of -dimensional Palatini action without second-class constraints
Merced Montesinos, Ricardo Escobedo, Jorge Romero +1
We carry out the canonical analysis of the -dimensional Palatini action with or without a cosmological constant introducing neither second-class constraints nor resor…
Barbero-like variables derived from Holst action
Merced Montesinos, Jorge Romero, Ricardo Escobedo +1
We work on a spacetime manifold foliated by timelike leaves. In this setting, we explore the solution of the second-class constraints arising during the canonical analysis of the H…
