Von-Karman scaling of proton and electron heating in turbulent plasma

Abstract:

Abstract: A self consistent description of plasma dissipation requires fully kinetic treatment. In recent publications, we have addressed how proton heating depends on large scale parameters [1,2] and how the system size simulated affects the plasma energetics [3]. Here, we study the relative heating of protons and electrons as it depends on large scale parameters. We also discuss the dependence of this relative heating on von-Karman decay rates, along with implications for turbulent dissipation challenge. An interesting possibility is that turbulent heating and heating in reconnection might be understood in a unified way [4].
