论文摘要
我们提出了弗拉索夫·马克斯韦(Vlasov-Maxwell)动力学理论的概括,该理论解释了强烈的电磁场。强烈的,可能是光学厚的等离子体分解为片段,每个等离子体包括带电的粒子以及其自生成的电磁场。假设弱的碎片间相关性,但构架内相关性很强,则得出了单碎片分布功能的平均场进化方程。我们还确定了方程式的哈密顿配方。通过在带电的粒子及其产生的场之间结合强相关性,新模型可捕获强辐射反应的效果。碎片动力学形式主义提供了一种吸引人的方法,可以建模异国情调的光 - 物质相互作用,例如非线性和多个康普顿散射。
We present a generalization of Vlasov-Maxwell kinetic theory that accounts for intense electromagnetic fields. A strongly-radiating, possibly optically-thick plasma is decomposed into fragments, each comprising a charged particle together with its self-generated electromagnetic field. Assuming weak inter-fragment correlations, but strong intra-fragment correlations, a mean-field evolution equation for the single-fragment distribution functional is derived. We also identify the equation's Hamiltonian formulation. By incorporating strong correlations between a charged particle and the field it generates, the new model captures the effects of strong radiation reaction non-perturbatively. The fragment kinetic formalism offers an attractive approach to modeling exotic light-matter interactions such as nonlinear and multiple Compton scattering.
