Abstract Many effects in the interaction between atoms and a cavity that are usually described 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 expressions 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.

Quantum matter built from nanoscopic lattices of atoms and photons (2018, background): “…noted that although a single atom can have a reasonably large optical depth of OD ∼ 0.1 (Darquie et al., 2005; Tey et al., 2008), this per-atom OD cannot be extended to ensembles as a tightly focused beam rapidly diverges in area (Tanji-Suzuki et al., 2011; Baragiola et al., 2014; Qi et al., 2016).”
