Running vacuum against the and tensions
Joan Sola, Adria Gomez-Valent, Javier de Cruz Perez +1
The cosmological term, , was introduced years ago by Einstein in his gravitational field equations. Whether is a rigid quantity or a dynamical variable in cosmology ha…
Stringy-Running-Vacuum-Model Inflation: from primordial Gravitational Waves and stiff Axion Matter to Dynamical Dark Energy
Nick E. Mavromatos, Joan Sola
In previous works we have derived a Running Vacuum Model (RVM) for a string Universe, which provides an effective description of the evolution of 4-dimensional string-inspired cosm…
String-Inspired Running Vacuum, the "Vacuumon", and the Swampland Criteria
Nick E. Mavromatos, Joan Solà, Spyros Basilakos
We elaborate further on the compatibility of the "vacuumon potential" that characterises the inflationary phase of the Running Vacuum Model (RVM) with the Swampland criteria. The w…
Particle and entropy production in the Running Vacuum Universe
Joan Sola, Hao Yu
We study particle production and the corresponding entropy increase in the context of cosmology with dynamical vacuum. We focus on the particular form that has been called "running…
Can dark energy be expressed as a power series of the Hubble parameter?
Mehdi Rezaei, Mohammad Malekjani, Joan Sola
In this work we examine the possibility that the dark energy (DE) density, can be dynamical and appear as a power series expansion of the Hubble rate (and its derivatives)…
Gravitational and Chiral Anomalies in the Running Vacuum Universe and Matter-Antimatter Asymmetry
Spyros Basilakos, Nick E. Mavromatos, Joan Sola
We present a model for the Universe in which quantum anomalies are argued to play an important dual role: they are responsible for generating matter-antimatter asymmetry, but also…
