Exchange effects in plasmas: the case of low-frequency dynamics
arXiv:1303.3389 · doi:10.1103/PhysRevE.88.063105
Abstract
Recently, there has been a surge in the interest of non-equilibrium collective quantum models, where particle dispersion and spin are examples of effects taken into account. Here, we derive a kinetic plasma model con- taining fermion exchange effects. Exchange interactions are of great importance in many systems, and have no classical analogy. Our model therefore constitute a possible probe of collective quantum phenomena in new regimes. As an example, we consider the influence of exchange effect on low frequency dynamics, in partic- ular ion acoustic waves. Comparisons to related computational techniques are given and the differences are highlighted. Furthermore, we discuss the applicability of our model, its limitations and possible extensions.
