Physical Review D, 2015•APSWe provide type IIB string embeddings of two axion variants of natural inflation. We use a
combination of RR 2-form axions as the inflaton field and have its potential generated by
nonperturbative effects in the superpotential. Besides giving rise to inflation, the models
developed take into account the stabilization of the compact space, an essential condition
for any semirealistic model of string inflation.
