    "abstract": "We demonstrate trapping of an ultracold gas of neutral atoms in a macroscopic\nac electric trap. Three-dimensional confinement is obtained by switching\nbetween two saddle-point configurations of the electric field. Stable trapping\nis observed in a narrow range of switching frequencies around 60 Hz. The\ndynamic confinement of the atoms is directly visualized at different phases of\nthe ac switching cycle. We observe about 10^5 Rb atoms in the 1 mm^3 large and\nseveral microkelvins deep trap with a lifetime of approximately 5 s.",
