    "abstract": "We derive a model to describe decoherence of atomic clouds in atom-chip traps\ntaking the excited states of the trapping potential into account. We use this\nmodel to investigate decoherence for a single trapping well and for a pair of\ntrapping wells that form the two arms of an atom interferometer. Including the\ndiscrete spectrum of the trapping potential gives rise to a decoherence\nmechanism with a decoherence rate $\\Gamma$ that scales like $\\Gamma \\sim\n1/r_0^4$ with the distance $r_0$ from the trap minimum to the wire.",
