偶极相互作用双原子光暗周期中的合作效应

Cooperative effects in the light and dark periods of two dipole-interacting atoms

Almut Beige, Gerhard C. Hegerfeldt

摘要:

如果一个原子能够表现出宏观的暗周期或电子搁置,那么一个由两个原子组成的驱动系统就有三种类型的荧光周期(暗、单强度和双强度)。我们建议使用这些荧光类型的平均持续时间作为一个简单和容易获得的合作效果的指标。作为一个例子,我们研究了两个偶极相互作用的V系统的模拟技术。我们发现,这两种类型的光周期的持续时间表现出显着的分离依赖的振荡,它们的变化与偶极-偶极耦合常数的实部的相位。

英文摘要:

If an atom is able to exhibit macroscopic dark periods, or electron shelving, then a driven system of two atoms has three types of fluorescence periods (dark, single and double intensity). We propose to use the average durations of these fluorescence types as a simple and easily accessible indicator of cooperative effects. As an example we study two dipole-interacting V systems by simulation techniques. We show that the durations of the two types of light periods exhibit marked separation-dependent oscillations and that they vary in phase with the real part of the dipole-dipole coupling constant.
