A Bose-Einstein condensate bouncing off a rough mirror
J. Phys.: Conf. Ser. 19 (2005) 151-57, proceedings of the Conference on Atoms and Molecules near Surfaces (CAMS), Heidelberg April 2005.


    We present experimental results and theoretical analysis of the diffuse reflection of a Bose-Einstein condensate from a rough mirror. The mirror is produced by a blue-detuned evanescent wave supported by a dielectric substrate. The results are carefully analysed via a comparison with a numerical simulation. The scattering is clearly anisotropic, more pronounced in the direction of the evanescent wave surface propagation, as predicted theoretically.
