Viable Curvaton Models from the Parameter
L. F. Guimarães, F. T. Falciano
We show how to build a curvaton inflationary model motivated by scale-dependent non-Gaussianities of cosmological perturbations. In particular, we study the change of sign in the $…
A quasi-matter bounce equivalent to Starobinsky inflation
L. F. Guimarães, F. T. Falciano, G. Brando
In this paper we construct a bounce model that mimics the Starobinsky inflationary model. Our construction relies on Wands' duality, which shows that the Mukhanov-Sasaki equation h…
Spacetime Singularities in Generalized Brans-Dicke Theories
G. Brando, F. T. Falciano, L. F. Guimaraes
We study the formation of classical singularities in Generalized Brans-Dicke theories that are natural extensions to Brans-Dicke where the kinetic term is modified by a new couplin…
Fermion Production in Bouncing Cosmologies
A. Scardua, L. F. Guimarães, N. Pinto-Neto +1
We address the issue of fermionic particle creation in cosmological bouncing models governed by General Relativity, but where the bounce itself takes place due to quantum effects.…
