Enhanced quadrupole effects for atoms in surface spiral beams with a thin dielectric waveguide
Recently, some physical research has recognized the coupling of optical phase singularity light with quadrupole-active atomic transitions. We show that a Laguerre-Gaussian beam, when completely internally reflected at the dielectric/vacuum interface, can generate a well-defined surface spiral beam w...
