TL;DR
This paper explores the thermodynamics of the universe bounded by the event horizon using a non-equilibrium approach, deriving entropy variations and analyzing dark energy models.
Contribution
It introduces a non-equilibrium thermodynamic framework for the universe's event horizon and evaluates entropy changes considering irreversible processes.
Findings
Entropy variation depends on irreversible process parameters
Two dark energy models are analyzed within this framework
Results highlight the thermodynamic behavior of the universe's horizon
Abstract
The present work deals with universe bounded by the cosmological event horizon as a thermodynamical system which is irreversible in nature.Using non-equilibrium thermodynamical approach the entropy variation on the event horizon has been evaluated.The additional term in the entropy variation depends on the irreversible process parameter.Finally,two dark energy models are presented and results are analyzed.
