Abstract: We consider single field chaotic inflationary models plus a cosine modulation term, as in axion monodromy models, and augment it by a light scalar field with similar cosine coupling. We show the power spectrum of… read more here.

DOI: 10.1103/physrevd.101.083521
Abstract: Short baseline neutrino experiments, like LSND and MiniBooNE experiments, pointed towards the existence of eV mass scale sterile neutrinos. To reconcile sterile neutrinos with cosmology self interaction between sterile neutrinos has been studied. We analysed… read more here.

Abstract: We propose a more general version of the trans-Planckian censorship conjecture (TCC) which can apply to models of inflation with a varying speed of sound. We find that inflation models with cS read more here.
