A modified potential can terminate constant-roll inflation and produce an oscillatory reheating phase, yielding a reheating temperature within a few orders of magnitude of the GUT scale.

abstract
We study the cosmological inflation and reheating in a teleparallel model of gravity. Reheating is assumed to be due to the decay of a scalar field to radiation during its rapid oscillation. By using cosmological perturbations during inflation, and subsequent evolutions of the Universe, we calculate the reheating temperature as a function of the spectral index and the power spectrum.

End of the constant-roll inflation, and the reheating temperature
