Abstract
Plasma beta is an important parameter characterizing dynamics of various
systems such as the solar wind, planetary magnetospheres, and accretion
disks. Dependence of some plasma properties such as spectral break,
relative proton-electron heating, and intermittency has been studied
using observations as well as simulations [1,2,3]. In this study, we
use particle-in-cell (PIC) simulations of turbulence to study various,
yet unexplored, aspects of this beta variation. We analyze kinetic range
electric fields, the variation of scale-to-scale energy transfer, and
higher order statistics with respect to plasma beta. Systematic trends
in the behavior of various quantities are discussed, and their
implications for kinetic plasma dissipation are examined. Finally, we
extend this approach to laminar reconnection, which shows turbulence
like properties of magnetic spectrum and energy cascade [4,5].
