Bridging Lagrangian and Eulerian fluctuations in electron MHD turbulence — •Martin Rieke and Rainer Grauer — Institut für Theor. Physik I, Ruhr-Universität Bochum

Electron MHD is especially suited for addressing the relation between Lagrangian and Eulerian fluctuations since this system allows a direct energy cascade in two space dimensions. Using the CUDA framework for GPU computing, high resolution and long time statistics can be achieved to determine transition probabilities between Eulerian and Lagangrian fluctuation. The results are compared to known models for Navier-Stokes turbulence.
