Safe Phantom Divide Crossing from Unscreened Non-Minimal Coupling to Gravity
Joel Argudo-Panes, Alex González-Fuentes, Adrià Gómez-Valent
Recent hints of dynamical dark energy, including a possible crossing of the phantom divide, have motivated the search for viable theoretical explanations. Scalar fields non-minimal…
XCDM: a running vacuum strategy for crossing the phantom divide
Joan Solà Peracaula, Adrià Gómez-Valent, Alex González-Fuentes
Composite dynamical dark energy (DDE) has recently been explored as an efficient way to help cure cosmological tensions through the so-called XCDM model (Gomez-Valent & Solà Per…
Exploring the interplay of late-time dynamical dark energy and new physics before recombination
Alex González-Fuentes, Adrià Gómez-Valent
Cosmological models exhibiting crossing of the phantom divide improve the fit to current data, suggesting late-time dark energy (DE) dynamics at CL. However, they favor lo…
Towards a unified quantum field theory of dark energy and inflation: unstable de Sitter vacuum and running vacuum
Joan Solà Peracaula, Àlex González-Fuentes, Cristian Moreno-Pulido
Inflation is a necessary cosmic mechanism to cure basic inconsistencies of the standard model of cosmology. These problems are usually `fixed' by postulating the existence of a sca…
Effective Phantom Divide Crossing with Standard and Negative Quintessence
Adrià Gómez-Valent, Alex González-Fuentes
Cosmic microwave background data from the {\it Planck} satellite, combined with baryon acoustic oscillation measurements from the Dark Energy Spectroscopic Instrument and Type Ia s…
Reconstruction of dark energy and late-time cosmic expansion using the Weighted Function Regression method
Alex González-Fuentes, Adrià Gómez-Valent
Recent data from multiple supernova catalogs and DESI, when combined with CMB, suggest a non-trivial evolution of dark energy (DE) at the CL. This evidence is typically qu…
Running vacuum and H^4-inflation
Joan Solà Peracaula, Cristian Moreno-Pulido, Alex González-Fuentes
Recent studies of QFT in cosmological spacetime indicate that the speeding up of the present universe may not just be associated with a rigid cosmological term but with a running o…
