在这项工作中，我们证明了考虑在密集原子系综中发展的简并塞曼亚能级之间的相关性的重要性。为了做到这一点，我们开发了一套能够模拟大量原子的方程，同时仍然包含简并塞曼亚能级之间的相关性。这组方程在单光子极限下是精确的，并且可以解释为文献中典型使用的耦合谐振子方程的推广。利用这些方程，我们证明了在足够密集的系统中，塞曼亚能级之间的相关性可以导致阵列和原子云中光子散射线形的非平凡差异。
In this work, we demonstrate the importance of considering correlations between degenerate Zeeman sublevels that develop in dense atomic ensembles. In order to do this, we develop a set of equations capable of simulating large numbers of atoms while still incorporating correlations between degenerate Zeeman sublevels. This set of equations is exact in the single-photon limit, and may be interpreted as a generalization of the coupled harmonic oscillator equations typically used the literature. Using these equations, we demonstrate that in sufficiently dense systems, correlations between Zeeman sublevels can cause non-trivial differences in the photon scattering lineshape in arrays and clouds of atoms.
