Flattening the inflatonʹs potential with quantum corrections

I show that a classical scalar potential with V″V ∼ 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 ∼ 0.8 can be obtained in other implementations.
