Torsion as a Gauge Field in a Lorentz-Chern-Simons Theory
Simón del Pino, Adolfo Toloza
We explore a model of gravity that arises from the consideration of the Chern-Simons form in 2+1 dimensions for a spin connection with a contorsion described by a scalar and a vect…
From Lorentz-Chern-Simons to Massive Gravity in 2+1 Dimensions
Simón del Pino, Gaston Giribet, Adolfo Toloza +1
We propose a generalization of Chiral Gravity, which follows from considering a Chern-Simons action for the spin connection with anti-symmetric contorsion. The theory corresponds t…
Black hole with a Dirac field in 3+1 dimensions
Adolfo Toloza
We study a complex Dirac field in the chiral representation minimally coupled to gravity in 3+1 dimensions in the context of Einstein-Cartan theory. Generically the matter content…
Cosmology with Scalar-Euler form Coupling
Adolfo Toloza, Jorge Zanelli
A coupling between the spacetime geometry and a scalar field involving the Euler four-form can have important consequences in General Relativity. The coupling is a four-dimensional…
Reflections on Cosmology: an Outsider's Point of View
Adolfo Toloza, Jorge Zanelli
Some of the assumptions of cosmology, as based on the simplest version of General Relativity, are discussed. It is argued that by slight modifications of standard gravitation theor…
Tachyon Field in Intermediate Inflation
Sergio del Campo, Ramon Herrera, Adolfo Toloza
The tachyonic inflationary universe model in the context of intermediate inflation is studied. General conditions for this model to be realizable are discussed. In the slow-roll ap…
