Slow-rolling scalar dynamics and as solution for the Hubble tension
Giovanni Montani, Nakia Carlevaro, Maria G. Dainotti
We construct a theoretical framework to interpret the Hubble tension by means of a slow-rolling dynamics of a self-interacting scalar field. In particular, we split the Friedmann e…
On the Effects of Tokamak Plasma Edge Symmetries on Turbulence Relaxation
Nakia Carlevaro, Giovanni Montani, Fabio Moretti
The plasma edge of a tokamak configuration is characterized by turbulent dynamics leading to enhanced transport. We construct a simplified 3D Hasegawa--Wakatani model reducing to a…
Metric gravity with dynamical dark energy as a scenario for the Hubble tension
Giovanni Montani, Mariaveronica De Angelis, Flavio Bombacigno +1
We introduce a theoretical framework to interpret the Hubble tension, based on the combination of a metric gravity with a dynamical dark energy contribution. The modified gr…
On the 3D turbulence regime in a Tokamak plasma edge
Giovanni Montani, Nakia Carlevaro
We derive a reduced model for the electrostatic turbulence in a Tokamak edge, when dealing with a resistive plasma and neglecting the spatial gradient of the background density whi…
