QCD CP-violation scenario for a revised cosmological dynamics: analysis of the binned Pantheon Sample of Super Novae Ia
Giovanni Montani, Nakia Carlevaro, Maria Giovanna Dainotti +1
We investigate a modified cosmological dynamics in which the Universe is composed of baryonic matter and a complex (classical) scalar field. The phase component of this field is id…
Analysis of non-diffusive avalanche transport of energetic particles
Nakia Carlevaro, Matteo V. Falessi, Giovanni Montani +1
The dynamics of energetic particles (EPs) interacting with Alfvén eigenmodes (AEs) for the ITER 15MA baseline scenario was described using a reduced 1D model in [Carlevaro et al.…
Modifying CDM dynamics via out-of-equilibrium axions: reconciling SH0ES and DESI values
Giovanni Montani, Luis A. Escamilla, Nakia Carlevaro +1
We investigate late-Universe dynamics in which the dark matter component is described by axion particles. The proposed framework departs from the standard CDM paradigm due to a…
Reproducing anomalous transport coefficients from electro-static tokamak edge turbulent dynamics
Fabio Moretti, Francesco Cianfrani, Nakia Carlevaro +1
Turbulent transport near the X-point of a large tokamak is examined using local, gradient-driven simulations that determine the saturated plasma profiles. The distribution of a rep…
Decay of quintessence into dark matter: mitigating the Hubble tension?
Giovanni Montani, Luis A. Escamilla, Nakia Carlevaro +1
We propose a revised cosmological scenario that extends the Cold Dark Matter (CDM) framework by incorporating metric gravity in the Jordan frame. In this model, the…
Two Dynamical Scenarios for Binned Master Sample Interpretation
Giovanni Montani, Elisa Fazzari, Nakia Carlevaro +1
We analyze two different scenarios for the late Universe dynamics, resulting into Hubble parameters deviating from the CDM, mainly for the presence of an additional free parame…
