Stochastic inflationary dynamics beyond slow-roll and consequences for primordial black hole formation
Guillermo Ballesteros, Julián Rey, Marco Taoso +1
We consider the impact of quantum diffusion on inflationary dynamics during an ultra-slow-roll phase, which can be of particular significance for the formation of primordial black…
Primordial black holes as dark matter and gravitational waves from single-field polynomial inflation
Guillermo Ballesteros, Julián Rey, Marco Taoso +1
We consider the possibility that the majority of dark matter in our Universe consists of black holes of primordial origin. We determine the conditions under which such black holes…
Detuning primordial black hole dark matter with early matter domination and axion monodromy
Guillermo Ballesteros, Julián Rey, Fabrizio Rompineve
We present a scenario that ameliorates the tuning problems present in models of primordial black hole dark matter from inflation. Our setup employs the advantages of gravitational…
