相对论性强等离子体波理论

On the Theory of Relativistic Strong Plasma Waves

Arsen G. Khachatryan

摘要:

研究了真空中离子运动和电子温度对接近光速的一维非线性等离子体波的影响。结果表明,尽管破波场对离子质量的依赖性很弱,但非线性相对论波长发生了本质的变化。非线性导致强等离子体波长的增加,而离子的运动导致波长的减小。采用流体力学方法和基于Vlasov-Poisson方程的动力学方法研究了热等离子体中的相对论性强等离子体波。预言了热等离子体中相对论孤子的存在。

英文摘要:

The influence of motion of ions and electron temperature on nonlinear one-dimensional plasma waves with velocity close to the speed of light in vacuum is investigated. It is shown that although the wavebreaking field weakly depends on mass of ions, the nonlinear relativistic wavelength essentially changes. The nonlinearity leads to the increase of the strong plasma wavelength, while the motion of ions leads to the decrease of the wavelength. Both hydrodynamic approach and kinetic one, based on Vlasov-Poisson equations, are used to investigate the relativistic strong plasma waves in a warm plasma. The existence of relativistic solitons in a thermal plasma is predicted.
