Instabilities in tensorial nonlocal gravity
Henrik Nersisyan, Yashar Akrami, Luca Amendola +3
We discuss the cosmological implications of nonlocal modifications of general relativity containing tensorial structures. Assuming the presence of standard radiation- and matter-do…
Endlessly flat scalar potentials and -attractors
Michal Artymowski, Javier Rubio
We consider a minimally-coupled inflationary theory with a general scalar potential containing a stationary point of maximal order . We show…
On the geometrical interpretation of scale-invariant models of inflation
Georgios K. Karananas, Javier Rubio
We study the geometrical properties of scale-invariant two-field models of inflation. In particular, we show that when the field-derivative space in the Einstein frame is maximally…
Higgs-Dilaton cosmology: Universality vs. criticality
Javier Rubio, Mikhail Shaposhnikov
The Higgs-Dilaton model is able to produce an early inflationary expansion followed by a dark energy dominated era responsible for the late time acceleration of the Universe. At tr…
