“…To this end, cold atoms need to be transported in a lossless, tightly confining potential in order to preserve the coherence properties of the matter wave. Extensive studies have been performed both theoretically [13,14,15,16] and experimentally [17,18,19,8,20] using different geometries of hollow glass capillaries and exploiting the confining potentials created by the ac-Stark shift of atoms in a detuned laser field. However, severe losses of the confining light, speckle patterns and multimode performance limited the useful guiding length.…”

We demonstrate the first guiding of cold atoms through a 88 mm long piece of photonic band gap fiber. The guiding potential is created by a far-off resonance dipole trap propagating inside the fiber with a hollow core of 12 µm. We load the fiber from a dark spot 85 Rb magneto optical trap and observe a peak flux of more than 10 5 atoms/s at a velocity of 1.5 m/s. With an additional reservoir optical dipole trap, a constant atomic flux of 1.5 × 10 4 atoms/s is sustained for more than 150 ms. These results open up interesting possibilities to study nonlinear light-matter interaction in a nearly one-dimensional geometry and pave the way for guided matter wave interferometry.
