Density contrast in the scalar-tensor extension of non-metricity gravity
Ganesh Subramaniam, Avik De, Jackson Levi Said
We present a novel derivation of scalar cosmological perturbations in the scalar-tensor extension of non-metricity gravity, where the non-metricity scalar is non-minimally coup…

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…

Probing symmetric teleparallel gravity in the early universe
Avik De, Dalia Saha, Ganesh Subramaniam +1
General theory of relativity can be equivalently formulated on a flat space-time associating a torsion-free affine connection of non-vanishing non-metricity scalar . In this pap…
