摘要:

原子与腔相互作用中的许多效应通常用量子力学术语(腔量子电动力学,腔QED)来描述,在经典框架下可以理解和定量分析。我们采用这种辐射偶极振子的经典图象,导出了自由空间和光学谐振腔中单原子和原子系综与高斯模耦合的显式表达式。腔QED的协同性参数被证明起着核心作用,并给出了几何解释。经典的分析产生透明的,直观的结果,是有用的分析应用的腔QED,如原子探测和计数,腔冷却,腔自旋压缩,腔自旋光力学,或相变与自组织的系综光系统。

英文摘要:

Many effects in the interaction between atoms and a cavity that are usually de-scribed in quantum mechanical terms (cavity quantum electrodynamics, cavity QED) can be understood and quantitatively analyzed within a classical framework. We adopt such a classical picture of a radiating dipole oscillator to derive explicit ex- pressions for the coupling of single atoms and atomic ensembles to Gaussian modes in free space and in an optical resonator. The cooperativity parameter of cavity QED is shown to play a central role, and is given a geometrical interpretation. The classical analysis yields transparent, intuitive results that are useful for analyzing applications of cavity QED such as atom detection and counting, cavity cooling, cavity spin squeezing, cavity spin optomechanics, or phase transitions associated with the self-organization of the ensemble-light system.
