Scalar-Tensor Symmetric Teleparallel Gravity: Reconstruct the Cosmological History with a Steep Potential
Ghulam Murtaza, Avik De, Andronikos Paliathanasis
Within the framework of scalar-non-metricity gravity, we introduce a steep potential together with a power-law coupling function and investigate whether the acceleration phases of…
Can an Extra Degree of Freedom in Scalar-Tensor Non-Metricity Gravity Account for the Evolution of the Universe?
Ghulam Murtaza, Avik De, Andronikos Paliathanasis +1
We investigate whether the extra scalar degree of freedom that arises in the second connection class of scalar-tensor non-metricity gravity can accurately replicate and potentially…
A generic dynamical system formulation for Bianchi-I cosmology with isotropic fluid in gravity
Ghulam Murtaza, Saikat Chakraborty, Avik De
In this article, we present a generic dynamical system formulation for Bianchi-I cosmology in the presence of an isotropic fluid within the coincident gauge connection branch and o…
Scalar perturbation and density contrast evolution in gravity
Ganesh Subramaniam, Avik De, Tee-How Loo +1
The symmetric teleparallel theory offers an alternative gravitational formulation which can elucidate events in the early and late universe without requiring the physical existence…
Cosmological reconstruction and CDM universe in gravity
Gaurav N. Gadbail, Avik De, P. K. Sahoo
Symmetric Teleparallel Gravity allows for the reformulation of gravity in the form of nonmetricity by vanishing the contorsion term in the generic affine connection. Our focus is o…
Non-metricity with bounday terms: gravity and cosmology
Avik De, Tee-How Loo, Emmanuel N. Saridakis
We formulate gravity and cosmology. Such a construction is based on the symmetric teleparallel geometry, but apart form the non-metricity scalar we incorporate in the…
