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…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
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…
Vacuum energy and cosmological constant in QFT in curved spacetime
Joan Solà Peracaula, Cristian Moreno-Pulido
The cosmological constant term (CC), , is a pivotal ingredient in the standard model of cosmology or CDM, but it is a rigid quantity for the entire cosmic history. This is un…
Dark energy in quantum field theory: Implications on modern cosmology
Cristian Moreno-Pulido
In this dissertation, the nature of Dark Energy (DE) is examined from both theoretical and phenomenological perspectives. The possibility of DE being a dynamic quantity in quantum…
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…
Running vacuum in QFT in FLRW spacetime: The dynamics of from the quantized matter fields
Cristian Moreno-Pulido, Joan Sola Peracaula, Samira Cheraghchi
Phenomenological work in the last few years has provided significant support to the idea that the vacuum energy density (VED) is a running quantity with the cosmological evolution…
Equation of state of the running vacuum
Cristian Moreno-Pulido, Joan Sola Peracaula
Recent studies of quantum field theory in FLRW spacetime suggest that the cause of the speeding up of the universe is the running vacuum (RV). Appropriate renormalization of the en…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
Renormalizing the vacuum energy in cosmological spacetime: implications for the cosmological constant problem
Cristian Moreno-Pulido, Joan Sola Peracaula
The renormalization of the vacuum energy in quantum field theory (QFT) is usually plagued with theoretical conundrums related not only with the renormalization procedure itself, bu…
Renormalized without terms
Cristian Moreno-Pulido, Joan Sola Peracaula
The cosmological constant term, , in Einstein's equations has been for three decades a building block of the concordance or standard CDM model of cosmology. Although the latt…
BD-CDM and Running Vacuum Models: Theoretical background and current observational status
Javier de Cruz Perez, Joan Sola Peracaula, Adria Gomez-Valent +1
We present an analysis of the Brans-Dicke cosmological model with a cosmological constant and cold dark matter (BD-CDM). We find that the BD-CDM is favored by the overall cos…
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…
Cosmology Intertwined II: The Hubble Constant Tension
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +90
The current cosmological probes have provided a fantastic confirmation of the standard Cold Dark Matter cosmological model, that has been constrained with unprecedented accurac…
Brans-Dicke cosmology with a - term: a possible solution to CDM tensions
Joan Sola, Adria Gomez-Valent, Javier de Cruz Perez +1
We present a full-fledged analysis of Brans-Dicke cosmology with a cosmological constant and cold dark matter (BD-CDM for short). We extend the scenarios where the current cosmo…
Running vacuum in quantum field theory in curved spacetime: renormalizing without terms
Cristian Moreno-Pulido, Joan Sola
The -term in Einstein's equations is a fundamental building block of the `concordance' CDM model of cosmology. Even though the model is not free of fundamental problems, they…
Brans-Dicke gravity with a cosmological constant smoothes out CDM tensions
Joan Sola, Adria Gomez-Valent, Javier de Cruz Perez +1
We analyze Brans-Dicke gravity with a cosmological constant, , and cold dark matter (BD-CDM for short) in the light of the latest cosmological observations on distant superno…
