The Effect of Coherent Structures on Stochastic Acceleration in MHD Turbulence
Kaspar Arzner, Bernard Knaepen, Daniele Carati +2
We investigate the influence of coherent structures on particle acceleration in the strongly turbulent solar corona. By randomizing the Fourier phases of a pseudo-spectral simulati…

Statistical Properties of Dissipative MHD Accelerators
Kaspar Arzner, Loukas Vlahos, Bernard Knaepen +1
We use exact orbit integration to investigate particle acceleration in a Gauss field proxy of magnetohydrodynamic (MHD) turbulence. Regions where the electric current exceeds a cri…

Thermal Conduction in Magnetized Turbulent Gas
J. Cho, A. Lazarian, A. Honein +3
Using numerical methods, we systematically study in the framework of ideal MHD the effect of magnetic fields on heat transfer within a turbulent gas. We measure the rates of passiv…
