Running Vacuum in the expanding Universe: a unified QFT paradigm for Inflation and Dark Energy

Joan Solà Peracaula

The concordance CDM model, based on a rigid -term for the entire cosmic history, has been in crisis for a long time. In our expanding Universe, an evolving with the ex…

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…

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…

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 o…

Phantom matter: a challenging solution to the cosmological tensions

Adria Gomez-Valent, Joan Sola Peracaula

The idea of composite dark energy (DE) is quite natural since on general grounds we expect that the vacuum energy density (associated with the cosmological term ) may appear in…
