TL;DR
This paper investigates a thawing dark energy model within coupled quintessence, analyzing how symmetry breaking influences the evolution of the equation of state parameter and deriving analytical solutions.
Contribution
It introduces a novel coupled quintessence framework with spontaneous symmetry breaking affecting dark energy dynamics and provides analytical solutions for the equation of state.
Findings
Symmetry breaking occurs when dark matter density drops below a critical value.
The equation of state parameter deviates from -1 due to symmetry breaking.
Analytical solutions for the evolution of the dark energy equation of state are derived.
Abstract
We consider the thawing model in the framework of coupled quintessence model. The effective potential has symmetry which is broken spontaneously when the dark matter density becomes less than a critical value leading the quintessence equation of state parameter to deviate from -1. Conditions required for this procedure are obtained and analytical solution for the equation of state parameter is derived.
