摘要: We consider the dynamics of electrons in combined strong laser and Coulomb fields. Under a timescale separation condition, we reduce this to guiding-center framework. More precisely, derive hierarchy models for based on averaging over fast motion electron using Lie transforms. The reduced obtain describe well different ionization channels, particular, conditions under which an is rescattered by ionic core or directly ionized. comparison between these highlights are best suited qualitative quantitative agreement with parent dynamics.
