论文摘要
我们已经开发了一种量子 - 质量计算方案，用于定量治疗在强激光脉冲中6D氢原子的不可分割的量子型动力学。在这种方法中，电子对量子进行机械处理，并经典地进行质量（CM）运动。因此，CM变量的电子和经典汉密尔顿方程的Schrödinger方程，由于强激光场刺激的相对论效应而异，并同时集成。在这种方法中，很自然地研究使用CM速度光谱作为用于检测内部电子量子动力学的经典``堆积''的想法。我们已经使用线性极化激光场中的氢原子进行了这样的分析，并发现激光脉冲后CM动能分布与电子动能的光谱密度之间存在很强的相关性。这表明可以通过测量CM动能的分布来检测电子的量子动力学。
We have developed a quantum-quasiclassical computational scheme for quantitative treating of the nonseparable quantum-classical dynamics of the 6D hydrogen atom in a strong laser pulse. In this approach, the electron is treated quantum mechanically and the center-of-mass (CM) motion classically. Thus, the Schrödinger equation for the electron and the classical Hamilton equations for the CM variables, nonseparable due to relativistic effects stimulated by strong laser fields, are integrated simultaneously. In this approach, it is natural to investigate the idea of using the CM-velocity spectroscopy as a classical ``build-up'' set up for detecting the internal electron quantum dynamics. We have performed such an analysis using the hydrogen atom in linearly polarized laser fields as an example and found a strong correlation between the CM kinetic energy distribution after a laser pulse and the spectral density of electron kinetic energy. This shows that it is possible to detect the quantum dynamics of an electron by measuring the distribution of the CM kinetic energy.
