Atomic Ferris wheel beams
arXiv:1702.07633 · doi:10.1103/PhysRevA.96.013622
Abstract
We study the generation of atom vortex beams in the case where an atomic wave-packet, moving in free space, is diffracted from a properly tailored light mask with a spiral transverse profile. We show how such a diffraction scheme could lead to the production of an atomic Ferris wheel beam.
