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 …

[HTML][HTML] New models and big bang nucleosynthesis constraints in f (Q) gravity

FK Anagnostopoulos, V Gakis, EN Saridakis… - The European Physical …, 2023 - Springer
The f (Q) theories of modified gravity arise from the consideration of non-metricity as the
basic geometric quantity, and have been proven to be very efficient in describing the late …

Late-time cosmology with phantom dark-energy in f (Q) gravity

A Lymperis - Journal of Cosmology and Astroparticle Physics, 2022 - iopscience.iop.org
Motivated by the exciting features and a recent proposed general form of the function of non-
metricity scalar Q, we investigate the cosmological implications in f (Q) gravity, through the …

Geodesic deviation, Raychaudhuri equation, Newtonian limit, and tidal forces in Weyl-type f(QT) gravity

JZ Yang, S Shahidi, T Harko, SD Liang - The European Physical Journal C, 2021 - Springer
We consider the geodesic deviation equation, describing the relative accelerations of
nearby particles, and the Raychaudhuri equation, giving the evolution of the kinematical …

Coupling metric-affine gravity to the standard model and dark matter fermions

C Rigouzzo, S Zell - Physical Review D, 2023 - APS
General relativity (GR) exists in different formulations, which are equivalent in pure gravity.
Once matter is included, however, observable predictions generically depend on the version …

Static spherically symmetric wormholes in gravity

M Tayde, Z Hassan, PK Sahoo, S Gutti - arXiv preprint arXiv:2206.01184, 2022 - arxiv.org
In this article we obtain wormhole solutions in the recently proposed extension of symmetric
teleparallel gravity called $ f (Q, T) $ gravity. Here, the gravitational Lagrangian $ L $ is …

Self-similar cosmological solutions in symmetric teleparallel theory: Friedmann-Lemaître-Robertson-Walker spacetimes

N Dimakis, M Roumeliotis, A Paliathanasis… - Physical Review D, 2022 - APS
The existence of self-similar solutions is discussed in symmetric teleparallel f (Q) theory for a
Friedmann-Lemaître-Robertson-Walker background geometry with zero and nonzero spatial …

Coupling metric-affine gravity to a Higgs-like scalar field

C Rigouzzo, S Zell - Physical Review D, 2022 - APS
General relativity (GR) exists in different formulations. They are equivalent in pure gravity but
generically lead to distinct predictions once matter is included. After a brief overview of …

Constraining f (Q, T) gravity from energy conditions

S Arora, JRL Santos, PK Sahoo - Physics of the Dark Universe, 2021 - Elsevier
We are living in a golden age for experimental cosmology. New experiments with high
accuracy precision are been used to constrain proposals of several theories of gravity, as it …

Spontaneous Lorentz symmetry breaking and one-loop effective action in the metric-affine bumblebee gravity

A Delhom, T Mariz, JR Nascimento… - … of Cosmology and …, 2022 - iopscience.iop.org
The metric-affine bumblebee model in the presence of fermionic matter minimally coupled to
the connection is studied. We show that the model admits an Einstein frame representation …
