到目前为止，光脉冲的载波包络相位（CEP）的作用通常在几个周期（低于10 fs）的制度中得到证明。在这里，通过模拟H+2和D+2的分子动力学，我们报告说，H+2和D+2的电子本地化表现出意想不到的强CEP依赖的多晶制度。我们的结果还表明，在多周期制度（15-20 fs）的电子局域化的不对称性高于在单周期（4 fs）的脉冲。通过监测原子核和电子波包的运动，讨论了这种违反直觉的现象。
Thus far, the role of the carrier-envelope phase (CEP) of a light pulse has generally been demonstrated in the few-cycle (sub-10 fs) regime. Here, by simulating the molecular dynamics of H+2 and D+2, we report that the electron localization of H+2 and D+2 exhibits unexpectedly strong CEP dependence in the multicycle regime. Our results also demonstrate that the electron localization asymmetry in the multicycle regime (15–20 fs) is higher than that in the single-cycle (4 fs) pulse. This counterintuitive phenomenon is discussed by monitoring the motions of both nuclear and electronic wavepackets.
