Intermittent Plasma TurbulenceA key issue in electrostatically driven intermittent plasma turbulence is particle trapping, which is associated with its patches of coherency in electron and ion phase space. The most plausible description of these coherent substructures is thereby provided by the spectrum of Privileged Cnoidal Electron & Ion Holes, which are nonBGK equilibrium solutions of the governing VlasovPoisson system. These modes, being extinguished by smooth (i.e. regular) trapped particle distributions, are challenging standard wave theory by superseding Landau's linear wave approach (e.g. with respect to the onset of structure formation). This underlying nonlinear picture of structure formation is further strengthened by the following new publications in 2018, 2019, 2020:
