Reconstructing inflation and reheating in $f(\phi)T$ gravity
Abstract
The reconstruction of an inflationary universe in the context of one gravity, in which corresponds to the trace of energy momentum tensor is studied. To realize this reconstruction during the inflationary epoch, we consider as attractor the scalar spectral index in terms of of the number of -folds , in the framework of the slow-roll approximation. By assuming a specific function together with the simplest attractor , we find different expressions for the reconstructed effective potential . Additionally, we analyze the era of reheating occurs after of the reconstruction obtained during the inflationary epoch. In this scenario we determine the duration and temperature during the reheating epoch, in terms of the equation of state parameter and the observational parameters. In this context, the different parameters associated to the reconstructed model are restricted during the scenarios of inflation and reheating by considering the recent astronomical observations.
