Review on f (Q) gravity

L Heisenberg - Physics Reports, 2024 - Elsevier
Recent years have witnessed a rise in interest in the geometrical trinity of General Relativity
and its extensions. This interest has been fuelled by novel insights into the nature of gravity …

Challenges for ΛCDM: An update

L Perivolaropoulos, F Skara - New Astronomy Reviews, 2022 - Elsevier
A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

In the realm of the Hubble tension—a review of solutions

E Di Valentino, O Mena, S Pan, L Visinelli… - … and Quantum Gravity, 2021 - iopscience.iop.org
The simplest ΛCDM model provides a good fit to a large span of cosmological data but

[HTML][HTML] Model-independent reconstruction of f (Q) non-metric gravity

S Capozziello, R D'Agostino - Physics Letters B, 2022 - Elsevier
We consider gravity mediated by non-metricity, with vanishing curvature and torsion. The
gravitational action, including an arbitrary function of the non-metric scalar, is investigated in …

Modified gravity and cosmology

EN Saridakis, R Lazkoz, V Salzano, PV Moniz… - 2021 - Springer
The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

Spherically symmetric configuration in gravity

RH Lin, XH Zhai - Physical Review D, 2021 - APS
General relativity can be formulated equivalently with a non-Riemannian geometry that
associates with an affine connection of nonzero nonmetricity Q but vanishing curvature R …

[HTML][HTML] Physical characteristics and maximum allowable mass of hybrid star in the context of f (Q) gravity

P Bhar, S Pradhan, A Malik, PK Sahoo - The European Physical Journal C, 2023 - Springer
In this study, we explore several new characteristics of a static anisotropic hybrid star with
strange quark matter (SQM) and ordinary baryonic matter (OBM) distribution. Here, we use …

Wormhole geometries in f(Q) gravity and the energy conditions

A Banerjee, A Pradhan, T Tangphati… - The European Physical …, 2021 - Springer
Following the recent theory of f (Q) gravity, we continue to investigate the possible existence
of wormhole geometries, where Q is the non-metricity scalar. Recently, the non-metricity …

Cosmology in gravity: A unified dynamical systems analysis of the background and perturbations

W Khyllep, J Dutta, EN Saridakis, K Yesmakhanova - Physical Review D, 2023 - APS
Motivated by the fact that cosmological models based on f (Q) gravity are very efficient in
fitting observational datasets at both background and perturbation levels, we perform a …

General covariant symmetric teleparallel cosmology

M Hohmann - Physical Review D, 2021 - APS
Symmetric teleparallel gravity theories, in which the gravitational interaction is attributed to
the nonmetricity of a flat, symmetric, but not metric-compatible affine connection, have been …
