Atom Manipulations by Enhanced Quadrupole Interaction

详细

We develop a theory that leads to the explanation of the atom manipulations due to active quadrupole interaction of twisted light with atoms at near-resonance frequencies. We demonstrate that the total mechanical effects of active quadrupole interaction on atoms just gives a rotational motion in the case of the configuration of a two counter-propagating beams. Typical parameters are assumed to determine both dissipative and quadrupole forces to obtain the trajectories for an atom.
