From stable to unstable anomaly-induced inflation
Tiberio de Paula Netto, Ana M. Pelinson, Ilya L. Shapiro +1
Quantum effects derived through conformal anomaly lead to an inflationary model that can be either stable or unstable. The unstable version requires a large dimensionless coefficie…
Gravitational Waves and Perspectives for Quantum Gravity
Ilya L. Shapiro, Ana M. Pelinson, Filipe de O. Salles
Understanding the role of higher derivatives is probably one of the most relevant questions in quantum gravity theory. Already at the semiclassical level, when gravity is a classic…
Gravitational waves and stability of cosmological solutions in the theory with anomaly-induced corrections
Julio C. Fabris, Ana M. Pelinson, Filipe de O. Salles +1
The dynamics of metric perturbations is explored in the gravity theory with anomaly-induced quantum corrections. Our first purpose is to derive the equation for gravitational waves…
On the scaling rules for the anomaly-induced effective action of metric and electromagnetic field
Ana M. Pelinson, Ilya L. Shapiro
The anomaly-induced effective action is a useful tool for deriving the contributions coming from quantum effects of massless conformal fields. It is well-known that such correction…
Dark energy perturbations and a possible solution to the coincidence problem
Javier Grande, Ana Pelinson, Joan Sola
We analyze some generic properties of the dark energy (DE) perturbations, in the case of a self-conserved DE fluid. We also apply a simple test (the "F-test") to compare a model to…
Revisiting the modified Starobinsky model with cosmological constant
Ana Pelinson
The Starobinsky model is a natural inflationary scenario in which inflation arises due to quantum effects of the massless matter fields. A modified version of the Starobinsky (MSt)…
