Parametrized Post-Newtonian Limit of Teleparallel Dark Energy Model

Understand

We study the post-Newtonian limit in the teleparallel equivalent of General Relativity with a scalar field which non-minimally couples to gravity.

• The metric perturbation is obtained from the vierbein field expansion with respect to the Minkowski background.
• Due to the structure of the teleparallel gravity Lagrangian, the potential of the scalar field shows no effect to the parametrized post-Newtonian parameters, and compatible results with Solar System observations are found.
