Time-dependent Probability Density Functions and Information Geometry in the Fusion L-H Transition
Eun-jin Kim, Rainer Hollerbach
We report a first study of time-dependent Probability Density Functions (PDFs) in the Low-to- High confinement mode (L-H) transition by extending the previous prey-predator-type mo…
Stability and instability of hydromagnetic Taylor-Couette flows
Günther Rüdiger, Marcus Gellert, Rainer Hollerbach +2
Decades ago S. Lundquist, S. Chandrasekhar, P.H. Roberts and R. J.~Tayler first posed questions about the stability of Taylor-Couette flows of conducting material under the influen…
Suppression of a kinematic dynamo by large shear
Aditi Sood, Rainer Hollerbach, Eun-jin Kim
We numerically solve the magnetic induction equation in a spherical shell geometry, with a kinematically prescribed axisymmetric flow that consists of a superposition of a small-sc…
Density-shear instability in electron MHD
Toby S Wood, Rainer Hollerbach, Maxim Lyutikov
We discuss a novel instability in inertia-less electron magneto-hydrodynamics (EMHD), which arises from a combination of electron velocity shear and electron density gradients. The…
Cascades in decaying three-dimensional electron magnetohydrodynamic turbulence
C. J. Wareing, R. Hollerbach
Decaying electron magnetohydrodynamic (EMHD) turbulence in three dimensions is studied via high-resolution numerical simulations. The resulting energy spectra asymptotically approa…
Forward and inverse cascades in decaying two-dimensional electron magnetohydrodynamic turbulence
C. J. Wareing, R. Hollerbach
Electron magnetohydrodynamic (EMHD) turbulence in two dimensions is studied via high-resolution numerical simulations with a normal diffusivity. The resulting energy spectra asympt…
