Plasma turbulence driven by wave-hole interaction
Gabriele Celebre, Mario Imbrogno, Sergio Servidio +1
Wave-obstacle diffraction is, par excellence, an example of transition to nonlinearity, generating turbulence and complexity in fluids. We present an idealized kinetic plasma regim…
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…
Flat-top electron velocity distributions driven by wave-particle resonant interactions
Sofia Zanelli, Silvia Perri, Martina Condoluci +6
The role of kinetic electrons in the excitation and sustainment of ion-bulk electrostatic waves in collisionless plasmas is investigated, with a focus on the physical mechanisms re…
On the decay instability of electron acoustic waves
F. Valentini, T. M. O'Neil, D. H. Dubin
Electron acoustic waves (EAWs) are nonlinear plasma modes characterized by electron trapping, which suppresses the usual Landau damping. Despite being predicted in the 1990s, their…
Energy conversion in turbulent weakly-collisional plasmas: Eulerian Hybrid Vlasov-Maxwell simulations
O. Pezzi, Y. Yang, F. Valentini +4
Kinetic simulations based on the Eulerian Hybrid Vlasov-Maxwell (HVM) formalism permit the examination of plasma turbulence with useful resolution of the proton velocity distributi…
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…
