超辐射中的相关性:合作效应的封闭形式方法

Correlation in superradiance: A closed-form approach to cooperative effects

S. F. Yelin, M. Kostrun, Tun Wang, M. Fleischhauer

摘要:

我们发展了一种新的方法来描述超辐射和相关的合作和集体效应的封闭形式。利用这种方法,我们得到了一个两原子主方程,其中任何复杂的原子能级,半经典耦合场和量子涨落的字段可以包括,至少在原则上。作为一个例子,我们考虑一个初始倒置的两级系统的动力学,并显示如何即使在一个简单的系统现象,如初始辐射爆发或扩大由于偶极-偶极相互作用发生,但它也是可能的,以估计人口的subradiant状态在辐射衰减。最后,我们发现只有关联,而不是纠缠是负责超辐射。

英文摘要:

We have developed a novel method to describe superradiance and related cooperative and collective effects in a closed form. Using the method we derive a two-atom master equation in which any complexity of atomic levels, semiclassical coupling fields and quantum fluctuations in the fields can be included, at least in principle. As an example, we consider the dynamics of an initially inverted two-level system and show how even such in a simple system phenomena such as the initial radiation burst or broadening due to dipole-dipole interactions occur, but it is also possible to estimate the population of the subradiant state during the radiative decay. Finally, we find that correlation only, not entanglement is responsible for superradiance.
