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…
