Thawing in a coupled quintessence model

General Relativity and Quantum Cosmology 2016-09-21 v2 High Energy Physics - Theory

Abstract

We consider the thawing model in the framework of coupled quintessence model. The effective potential has Z2Z_2 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.
