A Nanofiber-Based Optical Conveyor Belt for Cold Atoms
A Nanofiber-Based Optical Conveyor Belt for Cold Atoms. We demonstrate optical transport of cold cesium atoms over millimeter-scale distances along an optical nanofiber. The atoms are trapped in a one-dimensional optical lattice formed by a two-color evanescent field surrounding the nanofiber, far red- and blue-detuned with respect to the ...
