Shell Models for Magnetohydrodynamic Turbulence
Paolo Giuliani
We review the main properties of shell models for magnetohydrodynamic (MHD) turbulence. After a brief account on shell models with nearest neighbour interactions, the paper focuses…

Intermittency in plasma turbulence
V. Carbone, P. Giuliani, L. Sorriso-Valvo +4
Intermittency in fluid turbulence can be evidentiated through the analysis of Probability Distribution Functions (PDF) of velocity fluctuations, which display a strong non-gaussian…

Cascades in helical turbulence
P. D. Ditlevsen, P. Giuliani
The existence of a second quadratic inviscid invariant, the helicity, in a turbulent flow leads to coexisting cascades of energy and helicity. An equivalent of the four-fifth law f…
