YF Cai, S Capozziello, M De Laurentis… - Reports on Progress …, 2016 - iopscience.iop.org
Over recent decades, the role of torsion in gravity has been extensively investigated along
the main direction of bringing gravity closer to its gauge formulation and incorporating spin …

Accelerating gravity models constrained by recent cosmological data

VF Cardone, N Radicella, S Camera - Physical Review D—Particles, Fields …, 2012 - APS
Generalized teleparallel gravity, also referred to as f (T) gravity, has been recently proposed
as an extended theory of gravitation able to give rise to an accelerated expansion in a matter …

Constant-roll inflation in f (T) teleparallel gravity

A Awad, W El Hanafy, GGL Nashed… - … of Cosmology and …, 2018 - iopscience.iop.org
We investigate in detail the implications of the constant-roll condition on the inflationary era
of a scalar field coupled to a teleparallel f (T) gravity. The resulting cosmological equations …

f (T, 𝒯) gravity and cosmology

T Harko, FSN Lobo, G Otalora… - Journal of Cosmology …, 2014 - iopscience.iop.org
We present an extension of f (T) gravity, allowing for a general coupling of the torsion scalar
T with the trace of the matter energy-momentum tensor Script T. The resulting f (T, Script T) …

The effective field theory approach of teleparallel gravity, f (T) gravity and beyond

C Li, Y Cai, YF Cai, EN Saridakis - Journal of Cosmology and …, 2018 - iopscience.iop.org

Perturbations in non-flat cosmology for f(T) gravity

S Bahamonde, KF Dialektopoulos, M Hohmann… - The European Physical …, 2023 - Springer
The study of cosmological perturbation theory in f (T) gravity is a topic of great interest in
teleparallel gravity since this is one of the simplest generalizations of the theory that modifies …

Cosmography in gravity

S Capozziello, VF Cardone, H Farajollahi… - Physical Review D …, 2011 - APS
Based only on the assumption that the Universe is homogenous and isotropic on large
scales, cosmography is an ideal tool to investigate the cosmic expansion history in an …

New types of f(T) gravity

RJ Yang - The European Physical Journal C, 2011 - Springer
Recently f (T) theories based on modifications of teleparallel gravity, where torsion is the
geometric object describing gravity instead of curvature, have been proposed to explain the …

Nonminimal torsion-matter coupling extension of gravity

T Harko, FSN Lobo, G Otalora, EN Saridakis - Physical Review D, 2014 - APS
We construct an extension of f (T) gravity with the inclusion of a nonminimal torsion-matter
coupling in the action. The resulting theory is a novel gravitational modification, since it is …

Cosmological applications of gravity

G Kofinas, EN Saridakis - Physical Review D, 2014 - APS
We investigate the cosmological applications of F (T, TG) gravity, which is a novel modified
gravitational theory based on the torsion invariant T and the teleparallel equivalent of the …
