Anisotropic fluorescence signals retarded dipole-dipole interactions in a thermal atomic cloud

Year: 2026

Type: article

Abstract: We experimentally observe and theoretically explain anisotropic multiple quantum coherence signals in the fluorescence from dilute thermal potassium vapours, at room temperature and particle densities ∼ 10 8 cm − 3 . We identify the retarded part of the geometrically fully resolved inter-atomic, resonant dipole-dipole interaction as the crucial ingredient to theoretically reproduce all qualitative features of the experimental spectra.
