Generating the curvature perturbation with instant preheating
Tomohiro Matsuda
A new mechanism for generating the curvature perturbation at the end of inflaton has been investigated. The dominant contribution to the primordial curvature perturbation may be ge…
Brane inflation without slow-roll
Tomohiro Matsuda
The scenario of brane inflation without using the conventional slow-roll approximations has been investigated. Based on the mechanism of generating the curvature perturbations at t…
Vacuum energy reduction through destabilization: a unification of quintessence and a dynamical approach?
Tomohiro Matsuda
Although quintessence cosmologies seem to explain the amount of cosmological constant today, the required conditions are severe. For example, an extremely slowly varying and light…
Elliptic Inflation: Generating the curvature perturbation without slow-roll
Tomohiro Matsuda
There are many inflationary models in which inflaton field does not satisfy the slow-roll condition. However, in such models, it is always difficult to generate the curvature pertu…
PBH and DM from cosmic necklaces
Tomohiro Matsuda
Cosmic strings in the brane Universe have recently gained a great interest. I think the most interesting story is that future cosmological observations distinguish them from the co…
