Generalized curvature-matter couplings in modified gravity

T Harko, FSN Lobo - Galaxies, 2014 - mdpi.com
In this work, we review a plethora of modified theories of gravity with generalized curvature-
matter couplings. The explicit nonminimal couplings, for instance, between an arbitrary …

Cosmography in gravity

S Mandal, D Wang, PK Sahoo - Physical Review D, 2020 - APS
Cosmography is an ideal tool to investigate the cosmic expansion history of the Universe in
a model-independent way. The equations of motion in modified theories of gravity are …

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 …

Cosmological and solar system consequences of gravity models

H Shabani, M Farhoudi - Physical Review D, 2014 - APS
To find more deliberate f (R, T) cosmological solutions, we take our previous paper further by
studying some new aspects of the considered models via investigation of some new …

[图书][B] Extensions of f (R) Gravity: Curvature-Matter Couplings and Hybrid Metric-Palatini Theory

T Harko, FSN Lobo - 2018 - books.google.com
Recent cosmological observations have posed a challenge for traditional theories of gravity:
what is the force driving the accelerated expansion of the universe? What if dark energy or …

cosmological models in phase space

H Shabani, M Farhoudi - Physical Review D—Particles, Fields, Gravitation, and …, 2013 - APS
We investigate the cosmological solutions of f (R, T) modified theories of gravity for a perfect
fluid in a spatially Friedmann-Lemaître-Robertson-Walker metric through the phase-space …

Investigating physical existence of charged stellar models

E Demir, T Naseer, A Ashraf, E Güdekli - Chinese Journal of Physics, 2024 - Elsevier
This study aims at the detailed exploration of the internal structure of various anisotropic star
configurations interacting with an electromagnetic field within the framework of f (R, T, Q) …

Anisotropic compact stars with Karmarkar condition in energy-momentum squared gravity

M Sharif, MZ Gul - General Relativity and Gravitation, 2023 - Springer
The main objective of this paper is to examine the viability and stability of anisotropic
compact stellar objects adopting the Karmarkar condition in energy-momentum squared …

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) …
