The maximum photon emission rate in atomic ensembles scales universally as atom number times optical depth at fixed density, unifying ordered and disordered systems from independent emission to the Dicke limit.
Near-field probing of trapped atoms is inherently transient due to probe-induced heating that reduces coupling strength via increased position spread.
