摘要:

研究了强流电磁(EM)束与热相对论等离子体的相互作用。结果表明,热压力带来了一个根本性的变化的动力学-本地化,高振幅,电磁场结构,不能访问一个冷(但相对论)等离子体,现在可以形成在定义良好的条件下。计算了在纯电子等离子体中,自导引机制捕获电磁光束形成稳定的二维孤子结构的例子。

英文摘要:

Interaction of an intense electromagnetic (EM) beam with hot relativistic plasma is investigated. It is shown that the thermal pressure brings about a fundamental change in the dynamics - localized, high amplitude, EM field structures, not accessible to a cold (but relativisic) plasma, can now be formed under well- defined conditions. Examples of the trapping of EM beams in self-guiding regimes to form stable 2D solitonic structures in a pure e-p plasma are worked out.
