Single-Cycle Non-Sequential Double Ionization

摘要: Non-sequential double ionization (NSDI) is a process in which two electrons are ripped off an atom or molecule by strong laser field correlated manner. Although NSDI has been the subject of numerous experimental and theoretical studies over past three decades, exact mechanisms responsible for observed energy momentum sharing between generated process, not yet fully understood. The main reason lies fact that description complex many body dynamics govern exceedingly difficult. A particularly challenging task theory modeling time scales exceeding one period field. As result, most calculations restricted to single cycle. On side, contrast, kinematically complete experiments on single-cycle long prohibitively challenging. Therefore, comparison limited, so far, very qualitative level. We review recent results obtained from first cycle regime. illustrate insight gained these experiments, discuss how new data may facilitate verification models quantitative
