Onset of acceleration in a Universe initially filled by dark and baryonic matters in nonminimally coupled teleparallel model

TL;DR

This paper explores how a universe initially dominated by matter can evolve into an accelerating de Sitter phase through a nonminimally coupled teleparallel gravity model, highlighting the role of symmetry breaking.

Contribution

It introduces a nonminimally coupled quintessence model in teleparallel gravity demonstrating the transition from matter dominance to late-time acceleration.

Findings

Universe transitions to de Sitter space via symmetry breaking

Dark energy density remains negligible initially

Model explains onset of cosmic acceleration

Abstract

A nonminimally coupled quintessence dark energy in teleparallel model of gravity is considered. It is clarified how a matter dominated universe with initial negligible dark energy density can evolve to a late time de Sitter space-time via the $Z_2$ symmetry breaking.
