Nonlinear EMHD Physics

该奖项支持一个关于致密等离子体与磁场非线性相互作用的研究项目。这项研究将在一个大型的实验室等离子体中进行，在一个很少被探索的参数体系中，只有电子与磁场相互作用，而不是离子，而两种物质通过空间电荷电场耦合。两种具有时变电磁场的不同流体之间的相互作用导致了各种未知的非线性效应。这种参数体系称为电子磁流体力学。它的非线性效应可能导致磁湍流，这是一个固有的兴趣和认为是重要的磁重联。

This award supports a research program on the nonlinear interaction of dense plasmas with magnetic fields. The research will be done in a large laboratory plasma in a rarely explored parameter regime where only the electrons interact with the magnetic field, but not the ions, while both species are coupled via space-charge electric fields. The interplay between two different fluids with time-varying electromagnetic fields leads to a variety of unexplored nonlinear effects. This parameter regime is called electron magnetohydrodynamics. Its nonlinear effects may lead to magnetic turbulence which is of intrinsic interest and considered important in magnetic reconnection.
