A Complete Cosmological Scenario in Teleparallel Gravity

General Physics 2020-09-09 v2

Abstract

Teleparallel gravity is a modified theory of gravity in which the Ricci scalar RR of the Lagrangian replaced by the general function of torsion scalar TT in action. With that, cosmology in teleparallel gravity becomes profoundly simplified because it is second-order theory. The article present a complete cosmological scenario in f(T)f(T) gravity with f(T)=T+β(T)αf(T)=T+\beta(-T)^{\alpha}, where α,\alpha, and β\beta are model parameters. We present the profiles of energy density, pressure, and equation of state (EoS) parameter. Next to this, we employ statefinder diagnostics to check deviation from the Λ\LambdaCDM model as well as the nature of dark energy. Finally, we discuss the energy conditions to check the consistency of our model and observe that SEC violates in the present model supporting the acceleration of the Universe as per present observation.
