无碰撞等离子体中的超高马赫数静电激波

Very High Mach Number Electrostatic Shocks in Collisionless Plasmas

G. Sorasio, M. Marti, R. Fonseca, L. O. Silva

摘要:

本文提出了不同温度和密度的等离子体板碰撞产生无碰撞静电冲击的动力学理论。理论结果得到了自洽粒子模拟的证实,揭示了高马赫数($M \gg 10$)静电激波的形成和稳定传播,远高于静电激波经典理论的预测。

英文摘要:

The kinetic theory of collisionless electrostatic shocks resulting from the collision of plasma slabs with different temperatures and densities is presented. The theoretical results are confirmed by self-consistent particle-in-cell simulations, revealing the formation and stable propagation of electrostatic shocks with very high Mach numbers ($M \gg 10$), well above the predictions of the classical theories for electrostatic shocks.
