# Fourier–Hermite decomposition of the collisional Vlasov–Maxwell system: implications for the velocity-space cascade

@article{Pezzi2019FourierHermiteDO, title={Fourier–Hermite decomposition of the collisional Vlasov–Maxwell system: implications for the velocity-space cascade}, author={Oreste Pezzi and Francesco Valentini and Sergio Servidio and Enrico Camporeale and P Veltri}, journal={Plasma Physics and Controlled Fusion}, year={2019}, volume={61} }

Turbulence at kinetic scales is an unresolved and ubiquitous phenomenon that characterizes both space and laboratory plasmas. Recently, new theories, in situ spacecraft observations and numerical simulations suggest a novel scenario for turbulence, characterized by a so-called phase-space cascade—the formation of fine structures, both in physical and velocity-space. This new concept is here extended by directly taking into account the role of inter-particle collisions, modeled through the…
