An analogy between four parametrizations of the dark energy equation of state onto Physical DE Models

Abstract

In order to scrutinize the nature of Dark Energy, many Equations of State have been proposed. In this context we examine four popular models (the Chevallier-Polarski-Linder (CPL) model, Jassal model, Barboza & Alcaniz model and Wetterich model) in the field of quintessence and barotropic dark energy models, to compare with each other. We develop a theoretical method of constructing the quintessence potential directly from the four equations of state which describes the properties of the dark energy.
