Reconstructing inflation in scalar-torsion gravity
Manuel Gonzalez-Espinoza, Ramón Herrera, Giovanni Otalora +1
It is investigated the reconstruction during the slow-roll inflation in the most general class of scalar-torsion theories whose Lagrangian density is an arbitrary function …
Cosmological dynamics of dark energy in scalar-torsion gravity
Manuel Gonzalez-Espinoza, Giovanni Otalora
It is investigated the cosmological dynamics of scalar-torsion gravity as a dark energy model, where is the torsion scalar of teleparallel gravity and is a canonic…
Generating primordial fluctuations from modified teleparallel gravity with local Lorentz-symmetry breaking
Manuel Gonzalez-Espinoza, Giovanni Otalora
In the context of modified teleparallel gravity, we study the generation of primordial density fluctuations in a general scalar-torsion theory whose Lagrangian density is an arbitr…
Dynamical systems methods and statefinder diagnostic of interacting vacuum energy models
Grigoris Panotopoulos, Angel Rincon, Nelson Videla +1
We study three interacting dark energy models within the framework of four-dimensional General Relativity and a spatially flat Universe. In particular, we first consider two vacuum…
Slow-roll inflation in generalized scalar-torsion gravity
Manuel Gonzalez-Espinoza, Giovanni Otalora, Nelson Videla +1
We study the dynamics of inflation in a generalized scalar-torsion gravity scenario by assuming a canonical scalar field non-minimally coupled to torsion with a Galileon-type self-…
Growth of matter overdensities in non-minimal torsion-matter coupling theories
Manuel Gonzalez-Espinoza, Giovanni Otalora, Joel Saavedra +1
We study the evolution of cosmological perturbations around a homogeneous and isotropic background in the framework of the non-minimal torsion-matter coupling extension of g…
