Pole inflation and primordial black holes formation in Starobinsky-like supergravity
Shuntaro Aoki, Ryotaro Ishikawa, Sergei V. Ketov
We extend the Cecotti-Kallosh model of Starobinsky inflation in supergravity by adding a holomorphic function to the superpotential in order to generate a large peak in the power s…

On the Weyl gravity extension of Higgs inflation
Shuntaro Aoki, Hyun Min Lee
We consider the embedding of Higgs inflation with a non-minimal coupling into the Weyl gravity. In this model, the effective current-current interactions from the heavy Weyl gauge…

Reheating and Dark Matter Freeze-in in the Higgs- Inflation Model
Shuntaro Aoki, Hyun Min Lee, Adriana G. Menkara +1
We study the post-inflationary dynamics for reheating and freeze-in dark matter in the Higgs- inflation model. Taking the perturbative approach for reheating, we determine the…
