Linear and Nonlinear Theories of Cosmic Ray Transport — •Andreas Shalchi — Theoretische Physik IV,Ruhr-Universität Bochum
The transport of charged cosmic rays in plasmawave turbulence is a modern and interesting field of research. We are mainly interested in spatial diffusion parallel and perpendicular to a large scale magnetic field. During the last decades quasilinear theory was the standard tool for the calculation of diffusion coefficients. Through comparison with numerical simulations we found several major problems of transport theory. I will demonstrate that new nonlinear theories which were proposed recently can solve at least some of these problems.
