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…
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)…
