New Source for QCD Axion Dark Matter Production: Curvature Induced
Cem Eröncel, Yann Gouttenoire, Ryosuke Sato +2
We discuss a novel mechanism for generating dark matter from a fast-rolling scalar field, relevant for both inflation and rotating axion models, and apply it specifically to the (Q…

A universal bound on the duration of a kination era
Cem Eröncel, Yann Gouttenoire, Ryosuke Sato +2
We show that primordial adiabatic curvature fluctuations generate an instability of the scalar field sourcing a kination era. We demonstrate that the generated higher Fourier modes…
