The covariant formulation of f(T) gravity
(Iop Publishing Ltd, 2016-06-09)
We show that the well-known problem of frame dependence and violation of local Lorentz invariance in the usual formulation of f(T) gravity is a consequence of neglecting the role of spin connection. We re-formulate f(T) ...
ASYMPTOTIC PROPERTIES OF A SUPPOSEDLY REGULAR (DIRAC-BORN-INFELD) MODIFICATION OF GENERAL RELATIVITY

Causality in 3D massive gravity theories
(American Physical Society, 2017-05)
We study the constraints coming from the local causality requirement in various 2+1 dimensional dynamical theories of gravity. In topologically massive gravity, with a single parity noninvariant massive degree of freedom, ...
Torsion induces gravity
(American Physical Society, 2006-04)
In this work the Poincaré-Chern-Simons and anti-de Sitter-Chern-Simons gravities are studied. For both, a solution that can be cast as a black hole with manifest torsion is found. Those solutions resemble Schwarzschild and ...
Unavoidable conflict between massive gravity models and massive topological terms
(World Scientific Publ Co Pte Ltd, 2004-04-10)
Massive gravity models in (2 + 1) dimensions, such as those obtained by adding to Einstein's gravity the usual Fierz-Pauli, or the more complicated Ricci scalar squared (R-2), terms, are tree level unitary. Interesting ...

Holographic correlation functions in Critical Gravity
(Springer Verlag, 2017)
We compute the holographic stress tensor and the logarithmic energy-momentum tensor of Einstein-Weyl gravity at the critical point. This computation is carried out performing a holographic expansion in a bulk action ...
Quest for the extra degree of freedom in f ( T ) gravity
(American Physical Society, 2018-12)
It has recently been shown that f(T) gravity has n(n−3)/2+1 physical degrees of freedom (d.o.f.) in n dimensions, contrary to previous claims. The simplest physical interpretation of this fact is that the theory possesses ...
Minimal Log Gravity
(American Physical Society, 2015-01)
Minimal Massive Gravity (MMG) is an extension of three-dimensional Topologically Massive Gravity that, when formulated about Anti-de Sitter space, accomplishes to solve the tension between bulk and boundary unitarity that ...
