Particle Acceleration in Magnetized Shear-Driven Turbulence
Mingxuan Liu, Mateusz Ruszkowski, Ellen Zweibel +5
Shear flows, ubiquitous in space and astrophysical plasmas, can accelerate particles through turbulence excited by the Kelvin-Helmholtz instability. We present the first numerical…

Lévy Flights and Leaky Boxes: Anomalous Diffusion of Cosmic Rays
Naixin Liang, Siang Peng Oh
In classical diffusion, particle step-sizes have a Gaussian distribution. However, in superdiffusion, they have power-law tails, with transport dominated by rare, long Lévy flight…
