Optical Trapping of Cold Neutral Atoms Using a Two-Color Evanescent Light Field Around a Carbon Nanotube

We suggest a new schema of trapping cold atoms using a two-color evanescent light feld around a carbon nanotube. The two light felds circularly polarized sending through a carbon nanotube generates an evanescent wave around this nanotube. By evanescent effect, the wave decays away from the nanotube producing a set of trapping minima of the total potential in the transverse plane as a ring around the nanotube. This schema allows capture of atoms to a cylindrical shell around the nanotube. We consider some possible boundary conditions leading to the non-trivial bound state solution. Our result will be compared to some recent trapping models and our previous trapping models.
