    "abstract": "We derive scaling laws for the spin decoherence of neutral atoms trapped near\nconducting and superconducting plane surfaces. A new result for thin films\nsheds light on the measurement of Y.J. Lin, I. Teper, C. Chin, and V.\nVuleti\\\u0027{c} [Phys. Rev. Lett. \\textbf{92}, 050404 (2004)]. Our calculation is\nbased on a quantum-theoretical treatment of electromagnetic radiation near\nmetallic bodies [P.K. Rekdal, S. Scheel, P.L. Knight, and E.A. Hinds, Phys.\nRev. A \\textbf{70}, 013811 (2004)]. We show that there is a critical\natom-surface distance that maximizes the spin relaxation rate and we show how\nthis depends on the skin depth and thickness of the metal surface. In the light\nof this impedance-matching effect we discuss the spin relaxation to be expected\nabove a thin superconducting niobium layer.",
