摘要:

莫洛光谱学是一种光子统计光谱学,通过扫描从源系统散射的量子光获得。在这里,我们应用这种技术来检测弱的光与物质之间的相互作用腔和原子(或机械振荡器)时,包括强系统耗散。我们发现,当用从源散射的量子光在中心峰和每个边峰之间的中途激发靶腔时,可以高精度地测量弱相互作用。这最初来自于注入的量子光子的强相关性。原则上,我们的方案可以应用于JC模型描述的正常腔量子电动力学(QED)系统和光机系统。此外,即使在相互作用强度降低到很小的情况下,它也是实验的最新技术。

英文摘要:

Mollow spectroscopy is a photon statistics spectroscopy, obtained by scanning the quantum light scattered from a source system. Here, we apply this technique to detect the weak light-matter interaction between the cavity and atom (or a mechanical oscillator) when the strong system dissipation is included. We find that the weak interaction can be measured with high accuracy when exciting the target cavity by quantum light scattered from the source in the halfway between the central peak and each side peak. This originally comes from the strong correlation of the injected quantum photons. In principle, our proposal can be applied into the normal cavity quantum electrodynamics (QED) system described by JC model and optomechanical system. Furthermore, it is state-of-the-art for experiment even when the interaction strength is downed to a very small value.
