Super inflation mechanism with oscillating scalar fields in F(R,T) gravity

Abstract

The purpose of this study is to explain the super inflation scenario for the early universe with scalar field which is minimally coupled with theory of [Formula: see text] gravity, where [Formula: see text] is the Ricci curvature scalar and [Formula: see text] is the trace of the energy–momentum tensor (EMT). We consider the model [Formula: see text], where the curvature is minimally coupled with matter. All the modification terms are properly compacted in [Formula: see text], by means of a unified solution. After a vacuum inflation, it is observed that the scalar field oscillations via the power-term in potential [Formula: see text] naturally produce the quintessential type of dark energy. Then, we observe that the matter is created by this type of dark energy during inflation. Also, the spectral index parameter and the tensor-to-scalar ratio are examined for this inflation mechanism.
