Can Back-Reaction Prevent Eternal Inflation?
arXiv:1504.00867 · doi:10.1103/PhysRevD.92.043517
Abstract
We study the effects which the back-reaction of long wavelength fluctuations exert on stochastic inflation. In the cases of power-law and Starobinsky inflation these effects are too weak to terminate the stochastic growth of the inflaton field. However, in the case of the cyclic Ekpyrotic scenario, the back-reaction effects prevent the unlimited growth of the scalar field.
