Mimicking alternatives to inflation with interacting spectator fields
Guillem Domènech, Javier Rubio, Julius Wons
It has been argued that oscillatory features from spectator fields in the primordial power spectrum could be a probe of alternatives to inflation. In this work, we soften this clai…
Scale-invariant alternatives to general relativity. III. The inflation--dark-energy connection
Santiago Casas, Georgios K. Karananas, Martin Pauly +1
We discuss the cosmological phenomenology of biscalar-tensor models displaying a maximally symmetric Einstein-frame kinetic sector and constructed on the basis of scale symmetry an…
Gravitational waves from global cosmic strings in quintessential inflation
Dario Bettoni, Guillem Domènech, Javier Rubio
The combination of non-minimal couplings to gravity with the post-inflationary kinetic-dominated era typically appearing in quintessential inflation scenarios may lead to the spont…
Quintessential Affleck-Dine baryogenesis with non-minimal couplings
Dario Bettoni, Javier Rubio
We present a novel Affleck-Dine scenario for the generation of the observed baryon asymmetry of the Universe based on the non-trivial interplay between quintessential inflationary…
