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…
Second Order Perturbative Effects on the Acoustic Geometry
Nandan Roy, Shivani Singh, Sankhasubhra Nag +1
In this work, we have studied the effect of higher order perturbations, particularly the second order in details, on the sonic horizon. We have considered two different schemes of…
New general parametrization of quintessence fields and its observational constraints
Nandan Roy, Alma X. Gonzalez-Morales, L. Arturo Urena-Lopez
We present a new parameterization of quintessence potentials for dark energy based directly upon the dynamical properties of the equations of motion. Such parameterization arises n…
