DOI: 10.1088/1475-7516/2019/08/029

Abstract: 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-interaction. After obtaining the field equations for a flat FRW… read more here.

DOI: 10.1103/physrevd.98.064002

Abstract: We discuss the most general class of teleparallel scalar-torsion theories of gravity in their covariant formulation. The only restrictions we impose are the invariance of the action under diffeomorphisms and local Lorentz transformations, as well… read more here.

DOI: 10.1103/physrevd.98.064004

Abstract: We discuss a class of teleparallel scalar-torsion theories of gravity, which is parametrized by five free functions of the scalar field. The theories are formulated covariantly using a flat, but non-vanishing spin connection. We show… read more here.

DOI: 10.1142/s021988782650043x

Abstract: We investigate the holographic renormalization of scalar-torsion gravity in a fourdimensional bulk spacetime with non-minimal derivative coupling. The asymptotic behavior of the static equations leads to an anti-de Sitter geometry for negative cosmological constants, allowing… read more here.
