Effects of Turbulent Energy Exchange between Electrons and Ions on Global Temperature Profiles
T. Kato, H. Sugama, M. Honda
Microscale turbulence drives not only particle and heat transport but also energy exchange between different particle species. Previous local gyrokinetic studies have shown that tu…
Energy exchange between electrons and ions driven by ITG-TEM turbulence
T. Kato, H. Sugama, T. -H. Watanabe
In this study, the energy exchange between electrons and ions in ITG TEM turbulence is investigated using gyrokinetic simulations. The energy exchange in TEM turbulence is primaril…
Metriplectic bracket for guiding-center Vlasov-Maxwell-Landau theory
A. J. Brizard, H. Sugama
The metriplectic formulation of collisional guiding-center Vlasov-Maxwell-Landau theory is presented. The guiding-center Landau collision operator, which describes collisions invol…
Linear Landau damping, Schrödinger equation, and fluctuation theorem
Hideo Sugama
A linearized Vlasov-Poisson system of equations is transformed into a Schrödinger equation, which is used to demonstrate that the fluctuation theorem holds for the relative stochas…
