A Neural Operator Closure for Landau Damping in Electrostatic Plasma
Samuel Burles, Enrico Camporeale, Oreste Pezzi
We present a data-driven plasma fluid closure for both linear and nonlinear electrostatic Landau damping in one dimension. A Fourier Neural Operator (FNO) is trained online within…
Fourier-Hermite decomposition of the collisional Vlasov-Maxwell system: implications for the velocity space cascade
Oreste Pezzi, Francesco Valentini, Sergio Servidio +2
Turbulence at kinetic scales is an unresolved and ubiquitous phenomenon that characterizes both space and laboratory plasmas. Recently, new theories, {\it in-situ} spacecraft obser…
Coherent structures and spectral energy transfer in turbulent plasma: a space-filter approach
Enrico Camporeale, Luca Sorriso-Valvo, Francesco Califano +1
Plasma turbulence at scales of the order of the ion inertial length is mediated by several mechanisms, including linear wave damping, magnetic reconnection, formation and dissipati…
Approximate semi-analytical solutions for the steady-state expansion of a contactor plasma
E. Camporeale, E. A. Hogan, E. A. MacDonald
We study the steady-state expansion of a collisionless, electrostatic, quasi-neutral plasma plume into vacuum, with a fluid model. We analyze approximate semi-analytical solutions,…
Vlasov simulations of Kinetic Alfvén Waves at proton kinetic scales
C. L. Vasconez, F. Valentini, E. Camporeale +1
Kinetic Alfvén waves represent an important subject in space plasma physics, since they are thought to play a crucial role in the development of the turbulent energy cascade in the…
