论文摘要
我们开发一种量子光学形式主义，以处理放置在光腔中的二维原子。重要的是，与典型的处理相反，我们解释了由原子与外部非腔内限制模式的相互作用介导的合作偶极偶极效应。基于这样的观察，由于这些合作效应，在这些模式上的散射在很大程度上被抑制了，我们构建了一种通用的形式主义，独立于特定的腔体结构，并将其应用于一系列非饱和原子。通过进一步考虑原子运动，我们表明抑制阻尼可以导致放置在空腔内的原子阵列膜的光力学参数的有利缩放。发达的形式主义为进一步研究具有原子阵列的多体QED的基础是基础。
We develop a quantum optical formalism to treat a two-dimensional array of atoms placed in an optical cavity. Importantly, and in contrast to typical treatments, we account for cooperative dipole-dipole effects mediated by the interaction of the atoms with the outside, non-cavity-confined modes. Based on the observation that scattering to these modes is largely inhibited due to these cooperative effects, we construct a generic formalism, independent of the specific cavity structure, and apply it to an array of non-saturated atoms. By further considering the atomic motion, we show that the inhibited damping can lead to a favorable scaling of the optomechanical parameters of an atom-array membrane placed within a cavity. The developed formalism lays the basis for further investigation of many-body QED with atom arrays in transversely confined geometries.
