论文摘要
对一系列干涉测量实验的概念模拟用于确定对阈值高于阈值电离中多光子相移的强烈依赖。得出了相互作用相移的一个简单的经验法则，以解释光电产量的保守性及其绝对CEP依赖性。例如，发现相对于兔子实验而言，干涉率高于阈值电离实验的转移$π/4 $，并且在激光辅助的光电离实验中没有兔子学期，而奇数甚至谐波。因此，我们的工作有助于解决Attosent和自由电子激光科学中量子动态解释的问题。
Ab initio simulations of a range of interferometric experiments are used to identify a strong dependence on multiphoton phase shifts in above-threshold ionization. A simple rule of thumb for interaction phase shifts is derived to explain both the conservation of photoelectron yield and its absolute CEP-dependence. For instance, it is found that interferometric above-threshold ionization experiments are shifted by $π/4$ relative to RABBIT experiments, and that there is no RABBIT-term in a laser-assisted photoionization experiment with odd and even harmonics. Thus, our work helps to resolve the issues of interpretation of quantum dynamics in attosecond and free-electron laser sciences.
