Inflation Driven by Scalar-Neutrino Coupling in a Mass-Varying Neutrino Framework

Hemanshi Bundeliya, Gaurav Bhandari, S. D. Pathak +1

We propose a cosmological framework in which neutrino masses evolve dynamically through coupling with a scalar field that simultaneously drives inflation. The neutrino mass is mode…

Unified Lagrangian for Canonical and Non-Canonical Scalar Field

Tanisha Joshi, S. D Pathak

We proposed a generalized Lagrangian for three different classes of scalar fields namely quintessence( $I^\pm = - 1$ ), phantom( $I^\pm = 0$ ), and tachyonic ( $I^\pm = 1$ ) parameterized by $I^\pm$ . These…
