Breaking Eternal Inflation: Empirical Viability of a Spontaneous Collapse Scenario
MarÃa PÃa Piccirilli, Gabriel León, Rosa-Laura Lechuga-Solis +1
We revisit an inflationary scenario in which primordial inhomogeneities arise from a quantum collapse, a stochastic mechanism described in the context of quantum collapse theories…

Primordial power spectrum from an objective collapse mechanism: The simplest case
Martin Miguel Ocampo, Octavio Palermo, Gabriel León +1
In this work we analyzed the physical origin of the primordial inhomogeneities during the inflation era. The proposed framework is based, on the one hand, on semiclassical gravity,…
