标题： Effects of dispersive wave modes on charged particles transport

摘要： 太阳圈和星际介质中带电粒子的输运由粒子与磁不规则结构之间的相互作用所支配。 对于质子的输运，采用一个相当简单的模型即可，该模型使用遵循柯尔莫哥洛夫分布的线性阿尔芬波谱，通常能得到很好的结果。 即使磁静谱也可以使用。 对于电子输运的情况，粒子会与谱的高k端共振。 在这里，磁场涨落并不遵循线性色散关系，而是动理学区域发挥作用。 我们将讨论动理学区域内色散波涨落的相互作用，使用的是粒子束-单元代码。 特别是兰格等人（2013年）提出的粒子散射思想及其在PiC代码中的应用将被讨论。 离散区对电子输运的影响将被详细讨论。 显示英文摘要

摘要： The transport of charged particles in the heliosphere and the interstellar medium is governed by the interaction of particles and magnetic irregularities. For the transport of protons a rather simple model using a linear Alfv\'en wave spectrum which follows the Kolmogorov distribution usually yields good results. Even magnetostatic spectra may be used. For the case of electron transport, particles will resonate with the high-k end of the spectrum. Here the magnetic fluctuations do not follow the linear dispersion relation, but the kinetic regime kicks in. We will discuss the interaction of fluctuations of dispersive waves in the kinetic regime using a particle-in-cell code. Especially the scattering of particles following the idea of Lange et al. (2013) and its application to PiC codes will be discussed. The effect of the dispersive regime on the electron transport will be discussed in detail.
