Quark, lepton and right-handed neutrino production via inflation
Duarte Feiteira, Fotis Koutroulis, Oleg Lebedev +1
Inflationary expansion of space-time provides us with an efficient particle production mechanism in the Early Universe. The fermion production efficiency depends critically on the…

Cosmological gravitational particle production: Starobinsky vs Bogolyubov, uncertainties, and issues
Duarte Feiteira, Oleg Lebedev
We study production of free and feebly interacting scalars during inflation using the Bogolyubov coefficient and Starobinsky stochastic approaches. While the two methods agree in t…

Penrose and super-Penrose energy extraction from a Reissner-Nordström black hole spacetime with a cosmological constant through the BSW mechanism: Full story
Duarte Feiteira, José P. S. Lemos, Oleg B. Zaslavskii
The Penrose process, a process that transfers energy from a black hole to infinity, together with the BSW mechanism, which uses collisions of ingoing particles at the event horizon…
