Cosmic acceleration in screening hybrid quintessence model

General Relativity and Quantum Cosmology 2018-11-29 v3

Abstract

A formalism for the appearance of dark energy in the matter dominated era, leading to a persistent de Sitter expansion at the late time is proposed. Our framework is a hybrid quintessence model with a non-minimal coupling to the Ricci scalar. Coupling to the curvature triggers the dark energy evolution, while the coupling of scalar fields drives this evolution to a de Sitter stable fixed point. These occur via successive Z2Z_2 symmetry breakings.
