Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

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 …

We use Dirac's method for the quantization of constrained systems in order to quantize a
spatially flat Friedmann–Lemaître–Robertson–Walker spacetime in the context of f (Q) …

We developed the cosmological linear theory of perturbations for f (Q, T) gravity, which is an
extension of symmetric teleparallel gravity, with Q the non-metricity and T the trace of the …

In this paper, the cosmological model of the Universe has been presented in f (Q) f(Q) gravity
and the parameters are constrained from the cosmological data sets. At the beginning, a …

In this paper, we have presented an accelerating cosmological model of the Universe in an
extended symmetric teleparallel gravity or f (Q, T) gravity. The parametric form of the Hubble …

We study the cosmological inflation within the context of f (Q, T) gravity, wherein Q is the
nonmetricity scalar and T is the trace of the matter energy–momentum tensor. By choosing a …

In this study, we investigate the consequence of the constant-roll condition and examine the
role of a chosen form of f (Q, T) gravity, given by f (Q, T)= α Q 2+ σ T, in the cosmological …

In the context of the late time cosmic acceleration phenomenon, many geometrically
modified theories of gravity have been proposed in recent times. In this paper, we have …

In this work, we have developed an FLRW type model of a universe which displays transition
from deceleration in the past to the acceleration at the present. For this, we have considered …
