Diffraction by circular optical lattices

When a single two-level atom interacts with a pair of Laguerre-Gaussian beams with opposite helicity, this leads to an efficient exchange of angular momentum between the light field and the center-of-mass motion of the atom. When the radial motion is trapped by an additional potential, the wave func...

Zusammenfassung:When a single two-level atom interacts with a pair of Laguerre-Gaussian beams with opposite helicity, this leads to an efficient exchange of angular momentum between the light field and the center-of-mass motion of the atom. When the radial motion is trapped by an additional potential, the wave function of a single localized atom can be split into components that rotate in opposite direction. This suggests a scheme for atom interferometry without mirror pulses.
