The simplest ΛCDM model provides a good fit to a large span of cosmological data but
harbors large areas of phenomenology and ignorance. With the improvement of the number …

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 …

Singularities in any physical theory are either remarkable indicators of the unknown
underlying fundamental theory, or indicate a change in the description of the physical reality …

The present work studies one of Einstein's alternative formulations based on the
nonmetricity scalar Q generalized as f (Q) theory. More specifically, we consider the power …

We investigate the evolution of scalar perturbations in f (T) teleparallel gravity and its effects
on the cosmic microwave background (CMB) anisotropy. The f (T) gravity generalizes the …

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 …

In this paper, using Barrow entropy, we propose an interacting model of Barrow holographic
dark energy (BHDE). In particular, we study the evolution of a spatially flat FLRW universe …

We consider a generalized teleparallel theory of gravitation, where the action contains an
arbitrary function of the torsion scalar and a scalar field, f (T, ϕ), thus encompassing the …

We study the cosmological effects of adding terms of higher order in the usual energy-
momentum tensor to the matter Lagrangian of general relativity. This is in contrast to most …

The paper presents late time cosmology in f (Q, T) gravity where the dark energy is purely
geometric in nature. We start by employing a well motivated f (Q, T) gravity model, f (Q, T)= m …
