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…

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…
