Observational and Thermodynamic aspects of one-dimensional Dark Energy EoS parametrization models
Anirban Chatterjee, Yungui Gong
We investigate the observational and thermodynamic viability of Gong-Zhang (GZ) Type~I (GZ1) and Type~II (GZ2) dark-energy parametrizations using late-time cosmological probes incl…
A comprehensive dynamical and phenomenological analysis of structure growth in curvature-modulated coupled quintessence scenario
Anirban Chatterjee, Yungui Gong
We investigate an interacting dark energy-dark matter model within the quintessence framework, characterized by the coupling term , a…
Understanding curvature-matter interaction in viable dark energy models: A dynamical analysis approach
Anirban Chatterjee, Yungui Gong
We employ a linear stability analysis approach to explore the dynamics of matter and curvature-driven dark energy interactions within the framework of two types of viable gr…
Observational constraints on generic models of non-minimal curvature-matter coupling
Anirban Chatterjee, Akshay Panda, Abhijit Bandyopadhyay
We investigate two classes of non-minimally coupled curvature-matter models in the FLRW universe with a perfect fluid and analyze their cosmological implications using Supernova Ia…
Exploring the evolution of structure growth in the universe with field-fluid interactions through dynamical stability analysis
Anirban Chatterjee, Abhijit Bandyopadhyay, Debasish Majumdar
We investigate an interacting quintessence dark energy - dark matter scenario and its impact on structure formation by analyzing the evolution of scalar perturbations. The interact…
Dynamical analysis of coupled curvature-matter scenario in viable dark energy models at de Sitter phase
