Comparing Mass-Varying Neutrino Dark Energy Models with DESI DR2: Cosmological Constraints and Bayesian Evidence
Hemanshi Bundeliya, Gaurav Bhandari, Mohammad Yarahmadi +3
We investigate late-time cosmic acceleration in mass-varying neutrino (MaVaN) dark energy scenarios, where the neutrino mass is coupled to a dynamical quintessence field through a…
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…
Inflection Point of Minimally Coupled Tachyonic Scalar Field
Jaskirat Kaur, S. D. Pathak, Maxim Khlopov +1
In this paper, we investigate the behaviour of a minimally coupled tachyonic scalar field at inflection points in an accelerating universe. We consider the different expansion fact…
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(), phantom(), and tachyonic () parameterized by . These thr…
