N2 - The evanescent field surrounding nanoscale optical waveguidesoffers an efficient interface between light and mesoscopicensembles of neutral atoms. However, the thermalmotion of trapped atoms, combined with the strong radialgradients of the guided light, leads to a time-modulated couplingbetween atoms and the light mode, thus giving rise toadditional noise and motional dephasing of collective states.Here, we present a dipole force free scheme for coupling ofthe radial motional states, utilizing the strong intensity gradientof the guided mode and demonstrate all-optical couplingof the cesium hyperfine ground states and motionalsideband transitions. We utilize this to prolong the trap lifetimeof an atomic ensemble by Raman sideband cooling ofthe radial motion which, to the best of our knowledge, hasnot been demonstrated in nano-optical structures previously.This Letter points towards full and independent control ofinternal and external atomic degrees of freedom using guidedlight modes only.
