论文摘要
我们介绍了线性播种超高光的光学图片，该光学基于嵌入其他原子组成的分散有效培养基中的单个散射事件。这种线性分散理论在低密度和单散射状态下是有效的，即当令人兴奋的领域在很大程度上失调时。与偶极模型的比较显示了超级衰减率的完美一致性。然后，我们使用这种方法的两个优点。首先，我们与实验数据进行直接比较，没有任何免费参数，并显示出良好的定量一致性。其次，我们解决了运动原子的问题，可以通过将多普勒扩展到理论中来有效地模拟。特别是，我们讨论了如何在高温下恢复超沉淀。
We present an optical picture of linear-optics superradiance, based on a single scattering event embedded in a dispersive effective medium composed by the other atoms. This linear-dispersion theory is valid at low density and in the single-scattering regime, i.e., when the exciting field is largely detuned. The comparison with the coupled-dipole model shows a perfect agreement for the superradiant decay rate. Then we use two advantages of this approach. First we make a direct comparison with experimental data, without any free parameter, and show a good quantitative agreement. Second, we address the problem of moving atoms, which can be efficiently simulated by adding the Doppler broadening to the theory. In particular, we discuss how to recover superradiance at high temperature.
