Kinetic Simulations of Magnetized Turbulence in Astrophysical Plasmas
G. G. Howes, W. Dorland, S. C. Cowley +4
This letter presents the first ab initio, fully electromagnetic, kinetic simulations of magnetized turbulence in a homogeneous, weakly collisional plasma at the scale of the ion La…
Dissipation-Scale Turbulence in the Solar Wind
Gregory G. Howes, Steven C. Cowley, William Dorland +3
We present a cascade model for turbulence in weakly collisional plasmas that follows the nonlinear cascade of energy from the large scales of driving in the MHD regime to the small…
Preserving Monotonicity in Anisotropic Diffusion
Prateek Sharma, Gregory W. Hammett
We show that standard algorithms for anisotropic diffusion based on centered differencing (including the recent symmetric algorithm) do not preserve monotonicity. In the context of…
A Model of Turbulence in Magnetized Plasmas: Implications for the Dissipation Range in the Solar Wind
Gregory G. Howes, Steven C. Cowley, William Dorland +3
This paper studies the turbulent cascade of magnetic energy in weakly collisional magnetized plasmas. A cascade model is presented, based on the assumptions of local nonlinear ener…
An iterative semi-implicit scheme with robust damping
N. F. Loureiro, G. W. Hammett
An efficient, iterative semi-implicit (SI) numerical method for the time integration of stiff wave systems is presented. Physics-based assumptions are used to derive a convergent i…
Electron Heating in Hot Accretion Flows
Prateek Sharma, Eliot Quataert, Gregory W. Hammett +1
Local (shearing box) simulations of the nonlinear evolution of the magnetorotational instability in a collisionless plasma show that angular momentum transport by pressure anisotro…
