非均匀场对旋转对称分子的偏转
Deflection of Rotating Symmetric Molecules by Inhomogeneous Fields
摘要：
我们考虑偏转的旋转对称分子的不均匀的光学和静态电场，比较结果与线性分子的情况下，并发现新的奇异性的散射角的分布。详细分析了长/扁分子的散射过程，结果表明，利用短而强的飞秒激光脉冲可以有效地控制该过程。特别地，偏转分子的角色散可以通过激光诱导的分子预对准而显著减小。我们首先使用一个简单的经典模型来研究这个问题，然后通过更复杂的方法，包括绝热不变量的形式主义和直接数值模拟的欧拉-拉格朗日运动方程，找到类似的结果。建议的控制方案开辟了新的途径，许多应用涉及分子的聚焦，引导，并通过光学和静态场捕获。
英文摘要：
We consider deflection of rotating symmetric molecules by inhomogeneous optical and static electric fields, compare results with the case of linear molecules, and find new singularities in the distribution of the scattering angle. Scattering of the prolate/oblate molecules is analyzed in detail, and it is shown that the process can be efficiently controlled by means of short and strong femtosecond laser pulses. In particular, the angular dispersion of the deflected molecules may be dramatically reduced by laser-induced molecular pre-alignment. We first study the problem by using a simple classical model, and then find similar results by means of more sophisticated methods, including the formalism of adiabatic invariants and direct numerical simulation of the Euler-Lagrange equations of motion. The suggested control scheme opens new ways for many applications involving molecular focusing, guiding, and trapping by optical and static fields.
