Teleparallel gravity: from theory to cosmology

S Bahamonde, KF Dialektopoulos… - Reports on Progress …, 2023 - iopscience.iop.org
Teleparallel gravity (TG) has significantly increased in popularity in recent decades, bringing
attention to Einstein's other theory of gravity. In this Review, we give a comprehensive …

f (T) teleparallel gravity and cosmology

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 …

f(QT) gravity

Y Xu, G Li, T Harko, SD Liang - The European Physical Journal C, 2019 - Springer
We propose an extension of the symmetric teleparallel gravity, in which the gravitational
action L is given by an arbitrary function f of the non-metricity Q and of the trace of the matter …

Coupling matter in modified gravity

T Harko, TS Koivisto, FSN Lobo, GJ Olmo… - Physical Review D, 2018 - APS
We present a novel theory of gravity by considering an extension of symmetric teleparallel
gravity. This is done by introducing, in the framework of the metric-affine formalism, a new …

Dark energy cosmology: the equivalent description via different theoretical models and cosmography tests

K Bamba, S Capozziello, S Nojiri… - Astrophysics and Space …, 2012 - Springer
We review different dark energy cosmologies. In particular, we present the Λ CDM
cosmology, Little Rip and Pseudo-Rip universes, the phantom and quintessence …

gravity

T Harko, FSN Lobo, S Nojiri, SD Odintsov - Physical Review D—Particles …, 2011 - APS
We consider f (R, T) modified theories of gravity, where the gravitational Lagrangian is given
by an arbitrary function of the Ricci scalar R and of the trace of the stress-energy tensor T …

Relaxing cosmological tensions with a sign switching cosmological constant

Ö Akarsu, S Kumar, E Özülker, JA Vazquez - Physical Review D, 2021 - APS
Inspired by the recent conjecture originated from graduated dark energy that the Universe
has recently transitioned from anti–de Sitter vacua to de Sitter vacua, we extend the …

Modeling wormholes in gravity

P Moraes, PK Sahoo - Physical Review D, 2017 - APS
In this work, we propose the modeling of static wormholes within the f (R, T) extended theory
of gravity perspective. We present some models of wormholes, which are constructed from …

Dark energy stars and quark stars within the context of f (Q) gravity

P Bhar, JMZ Pretel - Physics of the Dark Universe, 2023 - Elsevier
In this work, we investigate the relativistic structure of compact stars within the framework of f
(Q) gravity, where Q is the nonmetricity scalar. In particular, we focus on the f (Q)= α Q+ β …

Energy conditions in gravity

M Sharif, A Ikram - The European Physical Journal C, 2016 - Springer
The aim of this paper is to introduce a new modified gravity theory named f (G, T) f (G, T)
gravity (GG and T are the Gauss–Bonnet invariant and trace of the energy-momentum …
