报告简介：
     Our recent experiments with cold Rb atoms around the nanofiber include the modification of the lifetime of the D2 line in the presence of the nanofiber and its relation to the single atom coupling. We find modifications of the lifetime that depend on the alignment of the dipole with respect to the nanofiber: parallel or perpendicular. We also explore collective effects (superradiance and sub-radiance) in the atomic decay from the atomic excited that depend on the number of atoms interacting in the evanescent mode of the nanofiber.
