论文摘要
我们报告了具有标记的载体 - eNVELOPE阶段的激烈的几个周期激光脉冲中氩二聚体的电离 - 碎片差异动力学的实验和理论研究。我们发现，从一个跨系统边界到另一个氩原子触发了相邻原子中的另一个氩原子亚周期电子相互作用动力学的野战驱动的电子传输过程。遥远实体及其含义之间的这个attosond电子转移过程表现为$ \ text {ar}^{ar}^{+}+\ text {ar}+text {ar}^{2+} $} $ fext {ar} $ fext {ar}+fragt {2+fragt {ar频道。我们的工作通过驱动分子间电子转移过程来通过对遥远分子上电子动力学的激发来控制分子化合物中的动力学的强场途径。
We report on an experimental and theoretical study of the ionization-fragmentation dynamics of argon dimers in intense few-cycle laser pulses with a tagged carrier-envelope phase. We find that a field-driven electron transfer process from one argon atom across the system boundary to the other argon atom triggers sub-cycle electron-electron interaction dynamics in the neighboring atom. This attosecond electron-transfer process between distant entities and its implications manifest themselves as a distinct phase-shift between the measured asymmetry of electron emission curves of the $\text{Ar}^{+}+\text{Ar}^{2+}$ and $\text{Ar}^{2+}+\text{Ar}^{2+}$ fragmentation channels. Our work discloses a strong-field route to controlling the dynamics in molecular compounds through the excitation of electronic dynamics on a distant molecule by driving inter-molecular electron-transfer processes.
