SGER: Nonlinear Theory of Anomalous Resistivity

磁重联在等离子体物理的许多领域都是一个重要的物理过程。它在太阳日冕、地球磁层顶和地球磁尾中尤为重要。人们认为，与等离子体湍流相关的异常电阻率在磁重联发生的物理过程中起着重要的甚至可能是关键的作用。反常电阻率已经用准线性理论研究了很多次，但还没有找到一个详细的非线性理论。本项目将发展由布曼等离子体不稳定性引起的异常电阻率的完全非线性理论。这项研究有很大的失败风险，但如果成功，异常电阻率的非线性理论有可能是革命性的。

Magnetic reconnection is an important physical processes in many areas of plasma physics. It is especially important in the solar corona, at Earth's magnetopause, and in Earth's magnetotail. It is thought that anomalous resistivity associated with plasma turbulence plays a significant and perhaps critical role in the physical processes by which magnetic reconnection takes place. Anomalous resisteivity has been examined many times in terms of quasi-linear theory but a detailed non-linear theory has yet to be found. This project will develop a fully non-linear theory of anomalous resistivity that arises from the Buneman plasma instability. There is a significant risk of failure associated with the research, but if successful a non-linear theory of anomalous resistivity has the potential to be transformative.
