Optical resonance shifts in the fluorescence of thermal and cold atomic gases
arXiv:1602.01037 · doi:10.1103/PhysRevLett.116.183601
Abstract
We show that the resonance shifts in the fluorescence of a cold gas of rubidium atoms substantially differ from those of thermal atomic ensembles that obey the standard continuous medium electrodynamics. The analysis is based on large-scale microscopic numerical simulations and experimental measurements of the resonance shifts in a steady-state response in light propagation.
