Inflationary Constraints on Late Time Modulus Dominated Cosmology
Koushik Dutta, Anshuman Maharana
We consider cosmological scenarios in which density perturbations are generated by the quantum fluctuations of the inflaton field at early times; the late time dynamics involves a…

N-flation in Supergravity
Kumar Das, Koushik Dutta
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-Plancki…
