Some Discussion on Thermodynamical Behaviour of Modified Chaplygin Gas

TL;DR

This paper investigates the thermodynamical properties of Modified Chaplygin Gas, deriving new parameter bounds and explicit relations between the state parameter and scale factor to better understand its role as Dark Energy.

Contribution

It provides new bounds on model parameters and derives an explicit relation between the state parameter and scale factor for Modified Chaplygin Gas.

Findings

New bounds on the model parameters

Explicit relation between state parameter and scale factor

Enhanced understanding of Modified Chaplygin Gas as Dark Energy

Abstract

On going good number of research works establish Modified Chaplygin Gas as one one of the most favoured candidates of Dark Energy. In our present work, new bound on the parameter space of associated model - parameter has been worked out with new explanation. Moreover, the explicit relation between the mysterious state parameter $w$ and scale factor $a(t)$ has been derived.
