Modulated inflation from kinetic term
We study modulated inflation from kinetic term. Using the MukhanovSasaki variable, it is possible to determine how mixing induced by the kinetic term feeds the curvature perturbation with the isocurvature perturbation. We show explicitly that the analytic result obtained from the evolution of the Mukhanov-Sasaki variable is consistent with the δN -formula. From our results, we find analytic con...
متن کاملNatural Supergravity Inflation
We identify a new mechanism in supergravity theories which leads to successful inflation without any need for fine tuning. The simplest model yields a spectrum of density fluctuations tilted away from scale-invariance and negligible gravitational waves. We demonstrate that this is consistent with the observed large-scale structure for a cold dark matter dominated, critical density universe. The...
متن کاملNatural Magnetogenesis from Inflation
We consider the gravitational generation of the massive Z boson field of the standard model, due to the natural breaking of its conformal invariance during inflation. The electroweak symmetry restoration at the end of inflation turns the almost scale-invariant superhorizon Z spectrum into a hypermagnetic field, which transforms into a regular magnetic field at the electroweak phase transition. ...

متن کاملSaving Natural Inflation
Slow-roll inflation requires the inflaton field to have an exceptionally flat potential, which combined with measurements of the scale of inflation demands some degree of finetuning. Alternatively, the flatness of the potential could be due to the inflaton’s origin as a pseudo-Goldstone boson, as in Natural Inflation. Alas, consistency with Planck data places the original proposal of Natural In...
