With a semiclassical quasistatic model we achieve insight into the complex dynamics of two correlated electrons under the combined influence of a two-center Coulomb potential and an intense laser field. The model calculation is able to reproduce experimental data of nitrogen molecules for a wide range of laser intensities from the tunneling to the over-the-barrier regime, and predicts a significant alignment effect on the ratio of double over single ion yield. The classical trajectory analysis allows us to unveil subcycle molecular double ionization dynamics.
通过一个半经典准静态模型，我们深入了解了在双中心库仑势和强激光场的联合影响下两个相关电子的复杂动力学。该模型计算能够在从隧穿到势垒贯穿区域的广泛激光强度范围内重现氮分子的实验数据，并预测了对双电离与单电离产率之比有显著的取向效应。经典轨迹分析使我们能够揭示亚周期分子双电离动力学。
