研究了原子介质中光散射的微观和平均场方法中超辐射和亚辐射的存在。我们发现，这些现象都存在于两种描述中，只有微小的数量差异，所以都不依赖于无序。特别地，它们在具有高谐振光学深度但远失谐光的介质中最突出，即，在单散射区。
The presence of superradiance and subradiance in microscopic and mean-field approaches to light scattering in atomic media is investigated. We show that these phenomena are present in both descriptions, with only minor quantitative differences, so neither rely on disorder. In particular, they are most prominent in media with high resonant optical depth yet far-detuned light, i.e., in the single-scattering regime.
