Exploring the Possibility of Interacting Quintessence Model as an Alternative to the CDM Model
Nandan Roy
This study examines interacting quintessence dark energy models and their observational constraints for a general parameterization of the quintessence potential, which encompasses…
Quintessence or Phantom: Study of scalar field dark energy models through a general parametrization of the Hubble parameter
Nandan Roy, Sangita Goswami, Sudipta Das
In this work we propose a simple general parametrization scheme of the Hubble parameter for the scalar field dark energy models. In our approach it is possible to incorporate both…
Tracker phantom field and a cosmological constant: dynamics of a composite dark energy model
Francisco X. Linares Cedeño, Nandan Roy, L. Arturo Ureña-López
In this work, we study tracker phantom dark energy models with a general parameterization of the scalar potentials. Our analysis also considers the scenario of having both phantom…
Generalized tracker quintessence models for dark energy
L. Arturo Urena-Lopez, Nandan Roy
We study the dynamical properties of tracker quintessence models using a general parametrization of their corresponding potentials, and show that there is a general condition for t…
The arbitrariness of potentials in interacting quintessence models
Nandan Roy, Kazuharu Bamba
We study the interacting quintessence model with two different types of interaction by introducing a general parameterization of the quintessence potentials. The form of the quinte…
