Adiabatic theory for molecular dynamics in intense laser fields

在这个项目中，我们发展了共线单电子双核分子模型的强场电离绝热理论。利用这个理论，它在一个版本中超越了Born-Oppenheimer近似，可以描述来自分子与超短和强激光场相互作用的光电子动量分布，这允许详细了解脉冲期间的动力学，并在控制化学反应中具有潜在的应用。并编制了数值程序对理论进行验证。这些测试发现，正如我们所预期的那样，该理论在缓慢变化的激光脉冲的限制下是准确的。该理论在描述干扰和同位素效应方面的潜在应用也得到了证实。

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.
