    "abstract": "A single atom strongly coupled to a cavity mode is stored by\nthree-dimensional confinement in blue-detuned cavity modes of different\nlongitudinal and transverse order. The vanishing light intensity at the trap\ncenter reduces the light shift of all atomic energy levels. This is exploited\nto detect a single atom by means of a dispersive measurement with 95%\nconfidence in 0.010 ms, limited by the photon-detection efficiency. As the atom\nswitches resonant cavity transmission into cavity reflection, the atom can be\ndetected while scattering about one photon.",
