    "abstract": "We present a first-principles derivation of spatial atomic-sublevel\ndecoherence near dielectric and metallic surfaces. The theory is based on the\nelectromagnetic-field quantization in absorbing dielectric media. We derive an\nexpression for the time-variation of the off-diagonal matrix element of the\natomic density matrix for arbitrarily shaped substrates. For planar\nmultilayered substrates we find that for small lateral separations of the\natom\u0027s possible positions the spatial coherence decreases quadratically with\nthe separation and inversely to the squared atom-surface distance.",
