Spacetime Hall-MHD turbulence at sub-ion scales: structures or waves?
Emanuele Papini, Antonio Cicone, Luca Franci +4
Spatiotemporal properties of two-dimensional (2D) Hall-magnetohydrodynamic turbulence at intermediate plasma are studied by means of Fast Iterative Filtering, a new technique…
Spectral transfer and Kármán-Howarth-Monin equations for compressible Hall magnetohydrodynamics
Petr Hellinger, Emanuele Papini, Andrea Verdini +4
We derive two new forms of the Kármán-Howarth-Monin equation for decaying compressible Hall magnetohydrodynamic (MHD) turbulence. We test them on results of a weakly-compressible,…
Evidence of a "current-mediated" turbulent regime in space and astrophysical plasmas
Luca Franci, Daniele Del Sarto, Emanuele Papini +6
How the turbulent energy cascade develops below the magnetohydrodynamic scales in space and astrophysical plasmas is a major open question. Here, we measure the power spectrum of m…
Multidimensional Iterative Filtering: a new approach for investigating plasma turbulence in numerical simulations
Emanuele Papini, Antonio Cicone, Mirko Piersanti +4
Turbulent space and astrophysical plasmas exhibit a complex dynamics, which involves nonlinear coupling across different temporal and spatial scales. There is growing evidence that…
Fast Magnetic Reconnection: Secondary Tearing Instability and Role of the Hall Term
Emanuele Papini, Simone Landi, Luca Del Zanna
Magnetic reconnection provides the primary source for explosive energy release, plasma heating and particle acceleration in many astrophysical environments. The last years witnesse…
Can Hall Magnetohydrodynamics explain plasma turbulence at sub-ion scales?
Emanuele Papini, Luca Franci, Simone Landi +3
We investigate the properties of plasma turbulence by means of two-dimensional Hall-magnetohydrodynamic (HMHD) and hybrid particle-in-cell (HPIC) numerical simulations. We find tha…
