Scalar field induced dynamical evolution in teleparallel gravity

Understand

In this paper, we investigate the role of scalar field potentials in the dynamical evolution of the Universe.

• A gravity theory with a non-minimally coupled scalar field with torsion in the geometrical action simulating effective dark energy is considered to study an extended matter bounce scenario.
• The dynamical behaviour of the equation of state parameter has been studied near the bouncing epoch.
• Keeping in mind the inflationary behaviour near the bounce, five different scalar field potential functions are explored, and their effect on the equation of state parameter is investigated.
