    "abstract": "When a single two-level atom interacts with a pair of Laguerre-Gaussian beams\nwith opposite helicity, this leads to an efficient exchange of angular momentum\nbetween the light field and the atom. When the radial motion is trapped by an\nadditional potential, the wave function of a single localized atom can be split\ninto components that rotate in opposite direction. This suggests a novel scheme\nfor atom interferometry without mirror pulses. Also atoms in this configuration\ncan be bound into a circular lattice.",
