Towards Natural Inflation in String Theory
  We 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 non perturbative effects in the superpotential.
Besides giving rise to inflation, the models developed take into account the
stabilization of the compact space, both in the KKLT and large volume scenario
regimes, an essential condition for any semi-realistic model of string
inflation.
