A solvable model of Vlasov-kinetic plasma turbulence in Fourier-Hermite phase space

Abstract:

A class of simple kinetic systems is considered, described by the 1D Vlasov--Landau equation with Poisson or Boltzmann electrostatic response and an energy source. Assuming a stochastic electric field, a solvable model is constructed for the phase-space turbulence of the particle distribution. The model is a kinetic analog of the Kraichnan--Batchelor model of chaotic advection. The solution of the model is found in Fourier--Hermite space and shows that the free-energy flux from low to high He...
