The production of a stochastic background of gravitational waves is a fundamental
prediction of any cosmological inflationary model. The features of such a signal encode …

Since inflationary perturbations must generically couple to all degrees of freedom present in
the early Universe, it is more realistic to view these fluctuations as an open quantum system …

There seems to exist agreement about the fact that inflation squeezes the quantum state of
cosmological perturbations and entangles modes with wavenumbers k⟶ and-k⟶ …

In this work we consider a wide variety of alternatives opened when applying the continuous
spontaneous localization (CSL) dynamical collapse theory to the inflationary era. The …

Inflation, a period of exponential expansion in the early Universe, is considered an important
part of the standard Λ CDM cosmological model, and plays a crucial role in explaining a …

The inflationary paradigm is extremely successful regarding predictions of temperature
anisotropies in the CMB. However, inflation also makes predictions for a CMB B-mode …

The hypothesis of the self-induced collapse of the inflaton wave function was introduced as
a candidate for the physical process responsible for the emergence of inhomogeneity and …

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 …

Cosmic inflation, which describes an accelerated expansion of the early Universe, yields the
most successful predictions regarding temperature anisotropies in the cosmic microwave …

We calculate the primordial power spectrum of tensor perturbations, within the emergent
universe scenario, incorporating a version of the Continuous Spontaneous Localization …
