AI 中文总结
研究具有电荷涨落的磁化等离子体中的电荷流不稳定性，通过推导色散关系和最大增长率，并用直接数值模拟验证，发现即使在μ零均值涨落、零电阻率和磁普朗特数为1时该不稳定性依然存在。
AI 中文摘要
我们提出了一种存在于具有电荷涨落的磁化等离子体中的线性不稳定性。它由与电荷化学势μ和体速度成正比的电流驱动。这种电荷流（C流）不稳定性在标准磁流体动力学及其手征扩展中迄今未被考虑。我们推导了其色散关系和最大增长率，并用直接数值模拟进行了验证。我们还表明，即使μ的零均值涨落、零电阻率和磁普朗特数为1时，C流不稳定性依然存在。
英文摘要
We present a linear instability in magnetized plasmas with charge fluctuations. It is driven by an electric current proportional to the charge chemical potential $μ$ and the bulk velocity. This charge-flow (C-flow) instability has hitherto not been considered in standard magnetohydrodynamics or its chiral extensions. We derive its dispersion relation and maximum growth rate, and confirm them with direct numerical simulations. We also show that the C-flow instability persists even for zero-mean fluctuations of $μ$, vanishing resistivity, and a magnetic Prandtl number of unity.
