Flattening the inflatons potential with quantum corrections

Abstract

I show that a classical scalar potential with V ''/V similar to 1 can be sufficiently flattened by quantum corrections to give rise to slow roll inflation. This provides perhaps the simplest way to generate an inflationary potential without fine-tuning. The most natural implementation of this idea produces an unviably small spectral index, but, for example, n similar to 0.8 can be obtained in other implementations.
