Scaling laws for the energy transfer in space plasma turbulence
R Marino, L Sorriso-Valvo - Physics Reports, 2023 - Elsevier
One characteristic trait of space plasmas is the multi-scale dynamics resulting from non-
linear transfers and conversions of various forms of energy. Routinely evidenced in a range …

Fast oscillations, collisionless relaxation, and spurious evolution of supernova neutrino flavor
Mounting evidence indicates that neutrinos likely undergo fast flavor conversion (FFC) in at
least some core-collapse supernovae. Outcomes of FFC, however, remain highly uncertain …

Pathways to dissipation in weakly collisional plasmas
Observed turbulence in space and astrophysics is expected to involve cascade and
subsequent dissipation and heating. Contrary to standard collisional fluid turbulence, the …

A comparison of alpha particle and proton beam differential flows in collisionally young solar wind
In fast wind or when the local Coulomb collision frequency is low, observations show that
solar wind minor ions and ion subpopulations flow with different bulk velocities …

Fully kinetic versus reduced-kinetic modeling of collisionless plasma turbulence
We report the results of a direct comparison between different kinetic models of collisionless
plasma turbulence in two spatial dimensions. The models considered include a first …

Radial evolution of the solar wind in pure high-speed streams: HELIOS revised observations
Spacecraft observations have shown that the proton temperature in the solar wind falls off
with radial distance more slowly than expected for an adiabatic prediction. Usually, previous …

Cascades and dissipative anomalies in nearly collisionless plasma turbulence
GL Eyink - Physical Review X, 2018 - APS
We develop first-principles theory of kinetic plasma turbulence governed by the Vlasov-
Maxwell-Landau equations in the limit of vanishing collision rates. Following an exact …
