N-flation in Supergravity
  We have constructed a large field N-flation model in the supergravity
framework. In this simple set-up, N fields collectively drive inflation where
each field traverses sub-Planckian field values. This has been realised with a
generalisation of the single field chaotic inflation in Supergravity.
Interestingly, despite of the presence of the field interactions, the dynamics
can be described in terms of an effective single field. The observable
predictions of our model i.e. tensor to scalar ratio r and scalar spectral
index n_s are akin to the chaotic inflation.
