The Peebles -- Vilenkin quintessential inflation model revisited
Jaume Haro, Jaume Amorós, Supriya Pan
We review the well-known Peebles-Vilenkin (PV) quintessential inflation model and discuss its possible improvements in agreement with the recent observations. The improved PV model…
Discrepancies between observational data and theoretical forecast in single field slow roll inflation
Jaume Amorós, Jaume de Haro
The PLANCK collaboration has determined values for the spectral parameters of the CMB radiation, namely the spectral index , its running , the running of the running $β_s…
The twilight of the single field slow rolling inflaton
Jaume Amoros, Jaume de Haro
We present an study from PLANCK2013+WP+BAO:CDM++ data, where 49 slow roll inflationary potentials are tested, showing that the theoretical value of the running provided…
Non-singular models of universes in teleparallel theories
Jaume de Haro, Jaume Amoros
Different models of universes are considered in the context of teleparallel theories. Assuming that the universe is filled by a fluid with equation of state (EoS) , for…
On the fate of the phantom dark energy universe in semiclassical gravity II: Scalar phantom fields
Jaume de Haro, Jaume Amoros, Emilio Elizalde
Quantum corrections coming from massless fields conformally coupled with gravity are studied, in order to see if they can lead to avoidance of the annoying Big Rip singularity whic…
