Composite Dark Energy and the Cosmological Tensions
Adria Gómez-Valent, Joan Solà Peracaula
The standard cosmological model currently in force, aka CDM, has been plagued with a variety of tensions in the last decade or so, which puts it against the wall. At the core of…
Running vacuum in the Universe: phenomenological status in light of the latest observations, and its impact on the and tensions
Joan Sola Peracaula, Adria Gomez-Valent, Javier de Cruz Perez +1
A substantial body of phenomenological and theoretical work over the last few years strengthens the possibility that the vacuum energy density (VED) of the universe is dynamical, a…
Quantum Anomalies in String-Inspired Running Vacuum Universe: Inflation and Axion Dark Matter
Spyros Basilakos, Nick E. Mavromatos, Joan Sola
In this letter, we elaborate further on a Cosmological "Running-Vacuum" type model for the Universe, suggested previously by the authors within the context of a string-inspired eff…
LXCDM cosmologies: solving the cosmological coincidence problem?
Javier Grande, Joan Sola, Hrvoje Stefancic
We explore the possibility of having a composite (self-conserved) dark energy (DE) whose dynamics is controlled by the quantum running of the cosmological parameters. We find that…
Density Perturbations for Running Cosmological Constant
Julio C. Fabris, Ilya L. Shapiro, Joan Sola
The dynamics of density and metric perturbations is investigated for the previously developed model where the decay of the vacuum energy into matter (or vice versa) is due to the r…
Effective equation of state for dark energy: mimicking quintessence and phantom energy through a variable Lambda
Joan Sola, Hrvoje Stefancic
While there is mounting evidence in all fronts of experimental cosmology for a non-vanishing dark energy component in the Universe, we are still far away from understanding its ult…
