Einstein-Cartan pseudoscalaron inflation, reheating and nonthermal leptogenesis
Carlo Di Benedetto, Alessandro Di Marco, Emanuele Orazi +1
We study the postinflationary dynamics of an Einstein-Cartan-Holst gravity-motivated inflationary scenario, known as Einstein-Cartan pseudoscalaron inflation, coupled to a type-I s…

Charge (in)stability and superradiance of Topological Stars
Andrea Cipriani, Carlo Di Benedetto, Giorgio Di Russo +2
We study linear massive scalar charged perturbations of Topological Stars in the fuzzball and in the black hole (Black String) regimes. The objects that naturally couple to the ele…
