Electron-Scale-Driven Turbulence by Negative-Density-Gradient in NSTX
C. Clauser, J. Candy, J. Parisi +7
Gyrokinetic simulations of an NSTX spherical-tokamak plasma reveal novel negative-density-gradient (NDG) drift waves at electron-gyroradius-scale that drive turbulent transport com…

Elucidating plasma dynamics in Hasegawa-Wakatani turbulence by information geometry
Johan Anderson, Eun-jin Kim, Bogdan Hnat +1
The impact of adiabatic electrons on drift-wave turbulence, modelled by the Hasegawa-Wakatani equations, is studied using information length. Information length is a novel theoreti…

Non-Linear Langevin and Fractional Fokker-Planck Equations for Anomalous Diffusion by Levy Stable Processes
Johan Anderson, Sara Moradi, Tariq Rafiq
The~numerical solutions to a non-linear Fractional Fokker--Planck (FFP) equation are studied estimating the generalized diffusion coefficients. The~aim is to model anomalous diffus…
