Multi-Natural Inflation in Supergravity
Michael Czerny, Tetsutaro Higaki, Fuminobu Takahashi
We show that the recently proposed multi-natural inflation can be realized within the framework of 4D supergravity. The inflaton potential mainly consists of two sinus…
Multi-Natural Inflation in Supergravity and BICEP2
Michael Czerny, Tetsutaro Higaki, Fuminobu Takahashi
We revisit the recently proposed multi-natural inflation and its realization in supergravity in light of the BICEP2 results. Multi-natural inflation is a single-field inflation mod…
Running Spectral Index from Large-field Inflation with Modulations Revisited
Michael Czerny, Takeshi Kobayashi, Fuminobu Takahashi
We revisit large field inflation models with modulations in light of the recent discovery of the primordial B-mode polarization by the BICEP2 experiment, which, when combined with…
Multi-Natural Inflation
Michael Czerny, Fuminobu Takahashi
We propose a multi-natural inflation model in which the single-field inflaton potential consists of two or more sinusoidal potentials that are comparable in size, but have differen…
