We explain how quadrupole-active atomic interactions be able to be enhanced once click here the neutral atom interacts with an evanescent winding light modes.The optical system presented is a semi-bounded space based on neutral atoms situated close to the evanescent Bessel-Gaussian modes.The quadrupole Rabi frequency (and hence the optical quadrupole potential) generated by such evanescent modes is large enough to be exploited in atoms manipulation.In particular, the atomic states in which the dipole transitions are prohibited My Mom Dad Is Well Trained Funny Cartoon Dog Gift For Dog Lover Personalized Shirt but the quadrupole transitions are permissible create the optical quadrupole potential of accessible value to play an important role.
It is also shown how such optical system acts to create of evanescent modes with $ ell gt 0 $ having an orbital angular momentum $ ell hbar $ in which the intensity distribution is restricted in the vicinity of the dielectric surface.
