Adiabatic theory for molecular dynamics in intense laser fields

在这个项目中，我们发展了一个分子的共线性单电子双核模型的强场电离绝热理论。有了这个理论，在一个版本中超越了玻恩-奥本海默近似，有可能描述来自分子与超短强激光场相互作用的光电子动量分布，这可以详细了解脉冲期间的动力学，具有控制化学反应的潜在应用。我们对该理论进行了分析，并建立了数值程序来验证该理论。这些测试发现，在缓慢变化的激光脉冲范围内，该理论是准确的，正如我们所期望的那样。还论证了该理论在描述干涉和同位素效应方面的潜在应用。

In this project we developed the adiabatic theory of strong-field ionization for a co-linear one-electron two-nucleus model of a molecule. With this theory, which in one version goes beyond the Born-Oppenheimer approximation, it is possible to describe the photo-electron momentum distribution coming from the interaction of molecules with ultra-short and strong laser fields, which allows for a detailed understanding of the dynamics during the pulse, with potential applications in controlling chemical reactions.We developed the theory analytically, and established numerical programs for testing the theory. These tests found the theory to be accurate in the limit of slowly varying laser pulses, as we expected. Potential applications of the theory for describing interference and isotope effects were also demonstrated.
