Primordial Black Holes as Dark Matter and the Tachyonic Trap During Inflation
Yuma S. Furuta, Mindaugas KarÄiauskas, Kazunori Kohri +1
We show that resonant processes during multi-field inflation can generate a large curvature perturbation on small scales. This perturbation naturally leads to the formation of prim…

Inflation models selected by the swampland distance conjecture with the Lyth bound
Yuma S. Furuta, Yuta Hamada, Kazunori Kohri
We investigate the extent to which the Swampland Conjecture can be employed to constrain large-field inflationary models from the perspective of quantum gravity consistency. In par…
