静电涨落和热涨落是非磁化非均匀等离子体中磁场的来源

Electrostatic and thermal fluctuations are the source of magnetic fields in unmagnetized inhomogeneous plasmas

Hamid Saleem

摘要:

指出在非均匀等离子体中,电子热涨落可以与离子声模耦合产生低频离子时标电磁波。如果温度和密度梯度彼此平行,这种电磁波就会变得不稳定,这在类似于恒星核心的激光等离子体中可能是这种情况。本理论模型与以前的调查的比较。最后将所得结果应用于经典的激光诱导等离子体。

英文摘要:

It is pointed out that electron thermal fluctuations can couple with the ion acoustic mode in an inhomogeneous plasma to generate a low frequency ion time scale electromagnetic wave. This electromagnetic wave can become unstable if the temperature and density gradients are parallel to each other which can be the case in laser-plasmas similar to stellar cores. The comparisons of the present theoretical model with the previous investigations are also presented. The final result is applied to a classical laser induced plasma for illustration.
