相位模量相关性的光化学应用

Photo-Chemical Applications of Phase-Modulus Interdependencies

Robert Englman, Asher Yahalom

摘要:

在对乔舒亚·乔特纳的赞誉之后,我们追溯了他在物理学著作中的化学背景的影响。在此过程中,我们注意到物理学在原理(或大尺度定律)方面的丰富性和化学的事实导向性。接下来,我们转向最近的激光诱导电子分离实验,并利用我们以前研究的(复)时域中的发展波包的分析性质,将优化的激光场的相位与其强度联系起来。这些结果可用于减少相强度控制反应动力学中脉冲优化的工作量。相位强度的相互依赖性也建立在模拟结果(获得与END算法)的光激发氢分子。

英文摘要:

After an accolade to Joshua Jortner, we trace the influences of his Chemistry background in his Physics writings. On the way, we note the richness of Physics in principles (or large-scale laws) and the fact-orientedness of Chemistry. Next we turn to a recent laser-induced electron-detachment experiment and utilize analytic properties of the developing wave-packet in the (complex) time domain, studied by us previously, to relate the phase of the optimized laser field to its intensity. It is suggested that these results can be used to reduce the labor of pulse optimization in phase-intensity controlled reaction dynamics. Phase-intensity interdependencies are also established in simulated results (obtained with the END-algorithm) for photo-excited hydrogen-molecules.
