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…
Extending the Numerical Flow Iteration to the multi-species Vlasov-Maxwell system through Hamiltonian Splitting
Rostislav-Paul Wilhelm, Fabio Bacchini, Sebastian Schöps +3
The Numerical Flow Iteration (NuFI) method has recently been proposed as a memory-slim while accurate in phase-space method for the electro-static Vlasov--Poisson system. It stores…
Formation of Suprathermal Electron Populations in the Expanding, Turbulent Solar Wind
Maximilien Péters de Bonhome, Fabio Bacchini, Luca Pezzini +1
Nonthermal features are ubiquitously observed in electron velocity distribution functions in the solar wind, yet their origin in the collisionless, turbulent, expanding solar-wind…
Reconnection-induced electron energization in magnetospheric Kelvin-Helmholtz dynamics
Silvia Ferro, Fabio Bacchini, Giuseppe Arrò +2
The Kelvin-Helmholtz instability (KHI) is a major driver of multiscale plasma dynamics at velocity shear layers, where it can promote the formation of current sheets and the onset…
Nonthermal Particle Acceleration by Magnetic Pumping in Pulsating Plasmas
Giuseppe Arrò, Vladimir Zhdankin, Fabio Bacchini
We present a new "pulsating box" setup to investigate particle acceleration in high-beta plasmas undergoing compression-expansion cycles. Our fully kinetic simulations show that pa…
Guide-Field-mediated Multiscale Instabilities in Relativistic Reconnection
Pranab J Deka, Fabio Bacchini, Muni Zhou +1
We investigate magnetic-energy dissipation, current-sheet dynamics, and nonthermal particle acceleration in three-dimensional relativistic reconnection in an electron--ion plasma w…
