Constraints on dark energy from the observed density fluctuations spectrum and supernova data
Reuven Opher, Ana Pelinson
One of the greatest challenges in cosmology today is to determine the nature of dark energy, the source of the observed present acceleration of the universe. High precision experim…
The anomaly-induced effective action and natural inflation
A. M. Pelinson, I. L. Shapiro, J. Sola +1
The anomaly-induced inflation (modified Starobinsky model) is based on the application of the effective quantum field theory approach to the Early Universe. We present a brief gene…
Vacuum effective action and inflation
J. C. Fabris, A. M. Pelinson, I. L. Shapiro
We consider vacuum quantum effects in the Early Universe, which may lead to inflation. The inflation is a direct consequence of the supposition that, at high energies, all the part…
Anomaly-induced effective action for gravity and inflation
J. C. Fabris, A. M. Pelinson, I. L. Shapiro
In the very early Universe the matter may be described by the free radiation, that is by the set of massless fields with negligible interactions between them. Then the dominating q…
