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

摘要

A nonminimally coupled quintessence dark energy in teleparallel model ofgravity is considered. It is clarified how a matter dominated universe withinitial negligible dark energy density can evolve to a late time de Sitterspace-time via the $Z_2$ symmetry breaking.
