Propagation of fast charged particles in artifically generated MHD turbulence: implications for cosmic-ray transport (F01)

本项目研究湍流如何决定粒子的扩散特性，潜在湍流的间歇性如何影响扩散，以及这些影响如何依赖于粒子的能量。在这里，通过添加均匀分量，生成人工湍流来模拟这些现实湍流场中的粒子输运。这样就可以确定作为能量和湍流比函数的扩散张量，并提供给a研究领域的项目。此外，还可以量化亚扩散和超扩散对天体物理特征的影响。

This project investigates how turbulence determines the diffusion properties of particles, how the intermittence of the underlying turbulence affects diffusion, and how these effects depend on the energy of the particles. Here, artificial turbulence is generated to simulate particle transport in these realistic turbulent fields with the addition of a homogeneous component. In this way, the diffusion tensor as a function of the energy and turbulence ratio can be determined and made available to the projects in Research Area A. Furthermore, it is possible to quantify the influence of sub- and superdiffusion on astrophysical signatures.
