Tensor-Induced Backreaction in Ultra-Slow-Roll Inflation
Alessandro Ciaiolo, Giovanni Marozzi
We discuss the impact of tensor-induced backreaction at second order in perturbation theory on primordial black holes production in single-field inflationary models, where the como…

Primordial black holes formation in a early matter dominated era from the pre-big bang scenario
Pietro Conzinu, Giovanni Marozzi
We discuss the production of primordial black holes in an early matter dominated era, which typically takes place in string inspired early universe cosmological models. In particul…

Gauge invariant averages for the cosmological backreaction
M. Gasperini, G. Marozzi, G. Veneziano
We show how to provide suitable gauge invariant prescriptions for the classical spatial averages (resp. quantum expectation values) that are needed in the evaluation of classical (…
