    • i the incident angle of the laser beam. To obtain coherent reflection the light has to be far-detuned and the surface has to be of very high quality. In general equation (1) will be only an approximation due to the imperfections in the mirror surface and the resulting interference between the evanescent wave and light scattered at these imperfections.

    • For an magnetic mirror [10,11] equation (1) is only an approximation for the magnitude of the magnetic field which is valid for κcursive Greek chi ≫ 1 with the characteristic decay length scale κ given by κ = 2π/d where d is the fundamental length scale of the periodic magnetisation at the surface. For κcursive Greek chi ∼ 1 one has to take the details of the surface magnetization into account and the spatial form of the repulsive potential can be more complicated. For details see: I.G.

    • Guides for matter waves are well-known in neutron optics [16], and were first demonstrated for atoms in 1992 by guiding a neutral atom along a current carrying wire [17]. Guiding in hollow fibers is an established technology in neutron optics [18] and was recently demonstrated for atoms [19].

    • We recently demonstrated guiding and trapping of cold Li atoms using a current carrying wire. We showed that a significant fraction of the atomic cloud can be captured, guided and even compressed using these wire guides: J. Denschlag, D. Cassettari, J. Schmiedmayer, Phys. Rev. Lett.
