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 …

Viable and stable compact stars in theory
In this paper, we study the viability and stability of anisotropic compact stars in the context of
f (Q) theory, where Q is non-metricity scalar. We use Finch–Skea solutions to investigate the …

New models and big bang nucleosynthesis constraints in f(Q) gravity
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 …

A class of static spherically symmetric solutions in f(Q)-gravity
M Calzá, L Sebastiani - The European Physical Journal C, 2023 - Springer
We analyze a class of topological static spherically symmetric vacuum solutions in f (Q)-
gravity. We considered an Ansatz ensuring that those solutions trivially satisfy the field …

A New Parametrization of Hubble Parameter in f (Q) f(Q) Gravity
In this paper, we examine the accelerated expansion of the Universe at late‐time in the
framework of f (Q) f(Q) gravity theory in which the non‐metricity scalar Q describes the …

[HTML][HTML] Metric-affine Myrzakulov gravity theories
In this paper, we review the so-called Myrzakulov Gravity models (MG-N, with N= I, II,…, VIII)
and derive their respective metric-affine generalizations (MAMG-N), discussing also their …

Constraining physical parameters of DESs via the secondary component of the GW190814 event and other self-bound NS pulsars in f(Q)-gravity theory
The spherically symmetric dark energy (DE) stellar model is presented here within the
context of the f (Q) theory of gravity. In order to develop the model, we take into account the …

Anisotropic solutions in symmetric teleparallel f Q-theory: Kantowski–Sachs and Bianchi III LRS cosmologies
We investigate the existence of anisotropic self-similar exact solutions in symmetric

Study of self-bound compact stars in gravity and observational constraints on the model parameters
The present study is based on f (T) gravity, where we impose possible observational
constraints on the model parameters to obtain physically plausible features of compact stars …
