Turbulent Magnetogenesis and Large-scale Magnetic Dynamo Amplification in Ion--electron Plasmas
Fabio Bacchini, Francesco Pucci, Sergio Servidio +2
Using fully kinetic simulations that capture unprecedentedly large (from electron to ion) scales, we study magnetogenesis driven by continuous large-scale forcing until nonlinear d…
Numerical simulations of waves and turbulence in coronal loops: observables and spectra
Fabio Feraco, Francesco Pucci, Claudio Meringolo +11
We investigate numerically the time evolution of velocity and magnetic field fluctuations in a coronal loop, focusing on the dynamics due to both phase mixing and turbulent cascade…
Numerical investigation of kinetic instabilities in BGK equilibria under collisional effects
Sofia Zanelli, Gabriele Celebre, Sergio Servidio +1
An unstable one-dimensional Bernstein-Greene-Kruskal (BGK) mode has been studied through high-precision numerical simulations. The initial turbulent, periodic equilibrium state is…
Long-living Equilibria in Kinetic Astrophysical Plasma Turbulence
Mario Imbrogno, Claudio Meringolo, Sergio Servidio +3
Turbulence in classical fluids is characterized by persistent structures that emerge from the chaotic landscape. We investigate the analogous process in fully kinetic plasma turbul…
Non-Maxwellianity of Ion Velocity Distributions in the Earth's Magnetosheath
Louis Richard, Sergio Servidio, Ida Svenningsson +6
We analyze the deviations from local thermodynamic equilibrium (LTE) of the ion velocity distribution function (iVDF) in collisionless plasma turbulence. Using data from the Magnet…
An Exact Turbulence Law For the Fluid Description of Fusion Edge Plasmas
Luisa Scarivaglione, Sergio Servidio
Understanding turbulence via simplified fluid models is crucial for optimizing magnetic confinement in tokamak devices. In this work, we propose a novel high-order turbulence law t…
