Loop-corrected scalar potentials and late-time acceleration in f(R) gravity
M. V. Pradosh Keshav, Arun Kenath
We construct an analytic f(R) gravity model that unifies early-time inflation with late-time cosmic acceleration within a single covariant framework. At high curvature, the model r…

Quintessence-Chameleon transitions in anisotropic Kiselev model of neutron stars
M. V. Pradosh Keshav, V. Jithesh, Kenath Arun
We investigate a chameleon scalar field dynamically interacting with a Kiselev-type metric, where the static anisotropic fluid part of the metric is replaced by a density-dependent…
