Modulated Inflation
Tomohiro Matsuda
We have studied modulated inflation that generates curvature perturbation from light-field fluctuation. As discussed in previous works, even if the fluctuation of the inflaton itse…

Hilltop Curvatons
Tomohiro Matsuda
We study ``hilltop'' curvatons that evolve on a convex potential. Hilltop curvatons evolving on the Hubble-induced potential are generic if supergravity is assumed in the theory. W…

Inhomogeneous preheating in multi-field models of cosmological perturbation
Tomohiro Matsuda
We consider inhomogeneous preheating in multi-field models of cosmological perturbation. After preheating, two fields are trapped at an enhanced symmetric point. One field is an os…
