在具有外诱导偶极矩的系统中诱导完全布居振荡
Inducing complete population oscillations in systems with externally induced dipole moments
摘要：
考虑了一个没有静态偶极矩的二能级系统，例如处于基态电子态的分子$H_2$。如果施加足够强的外场，它将动态地扭曲这样的系统，并为其提供依赖于时间（和场）的偶极矩。虽然这是不可能的，在无失真的系统中，没有耦合到外部场的偶极分量，在它诱导的偶极矩，这样的系统的旋转和振动动力学可以使用激光操纵。在这项工作中，考虑了一个系统中，外部扰动动态诱导跃迁偶极矩之间只有两个不同的水平。这项工作的目的是展示如何可以分析设计的驱动脉冲，这将产生两个级别之间的拉比一样的完整的人口振荡。
英文摘要：
A two level system is considered which has no static dipole moment, e.g. molecule $H_2$ in its ground electronic state. If strong enough external field is applied, it will dynamically distort such a system and supply it with time (and field) dependent dipole moment. Although it is impossible to do so in the undistorted system which has no coupling to the dipole component of the external field, having induced in it a dipole moment, the rotational and vibrational dynamics of such system can be manipulated using lasers. In this work, a system is considered in which the external perturbation dynamically induces the transition dipole moment between only two distinct levels. The aim of the work is to show how the driving pulse can be analytically designed, that will produce Rabi-like complete population oscillations between the two levels.
