The collective response of an atomic ensemble is shaped by its macroscopic environment. We demonstrate this effect in the near-resonant transmission of light through a thermal rubidium vapor confined in a planar nanocavity. Our model reveals density-dependent line shifts and broadenings beyond continuous electrodynamics models that oscillate with cavity width and have been observed in recent experiments. We predict that the amplitudes of these oscillations can be controlled by coatings that modify the cavity's finesse.

平面纳米腔中的集体偶极-偶极相互作用

原子整体的集体响应受其宏观环境的影响。我们通过封闭在平面纳米腔中的热thermal蒸气在光的近共振传输中证明了这种效应。我们的模型揭示了密度依赖的线位移和拓宽，超过了随腔宽度振荡的连续电动力学模型，并且在最近的实验中已经观察到。我们预测，这些振荡的幅度可以通过改变型腔精细度的涂层来控制。
