Atomic funnel with evanescent waves

Summary form only given. Cold atoms are expected to be applied to experiments on quantum motion, topological phenomena, cavity QED, and so on. Most of the interesting experiments require precise control on atomic motion. We have proposed the atomic waveguide by evanescent waves to enable the precise one-dimensional manipulation of atoms. The atomic waveguide is composed of a cylindrical-core hollow fiber with a hollow diameter of a few microns. The attachment of a funnel for atoms should be effective in coupling atoms to the atomic waveguide. In this work we present a novel scheme of the atomic funnel based on the dipole force from evanescent waves. Compared to the 2D MOT funnel, the evanescent-wave funnel has a further advantage of acting as a gravitational trap.
