“…The reflection of atoms with relatively high kinetic energy has been demonstrated using steep potentials realised with evanescent waves [282,283,284,285,286,287] and periodic magnetic surfaces [288,289,290,291,292,293,294,295,296,297,298]. These elements however critically depend on their surface roughness, which often hinders a purely specular reflection.…”

Abstract. This review discusses progress in the new field of coherent matter waves, in particular with respect to Bose-Einstein condensates. We give a short introduction to Bose-Einstein condensation and the theoretical description of the condensate wavefunction. We concentrate on the coherence properties of this new type of matter wave as a basis for fundamental physics and applications. The main part of this review treats various measurements and concepts in the physics with coherent matter waves. In particular we present phase manipulation methods, atom lasers, nonlinear atom optics, optical elements, interferometry and physics in optical lattices. We give an overview of the state of the art in the respective fields and discuss achievements and challenges for the future. § To whom correspondence should be addressed (sengstock@physnet.uni-hamburg.de) Physics with coherent matter waves 2

“…The phenomena have been realized as well experimentally [7]. The increased dynamical stability in the surface traps needed to develop RTM has extended the limits of the experiments from a few bounces [8,9,10] to even realize Bose-Einstein condensation of atoms using an optical reflecting surface [11] MOT is placed at a certain height above the evanescent wave atomic mirror. The mirror for the atoms results due to the total internal reflection of the incident laser light field from the surface of the dielectric film.…”

In order to probe nanostructures on a surface we present a microscope based on the quantum recurrence phenomena. A cloud of atoms bounces off an atomic mirror connected to a cantilever and exhibits quantum recurrences. The times at which the recurrences occur depend on the initial height of the bouncing atoms above the atomic mirror, and vary following the structures on the surface under investigation. The microscope has inherent advantages over existing techniques of scanning tunneling microscope and atomic force microscope. Presently available experimental technology makes it possible to develop the device in the laboratory.

“…1(b). This was first demonstrated as a method for retroreflecting cold atoms by Roach et al [12], using an audio tape with sine waves recorded on it, and by Sidorov et al [13] using an array of permanent magnets. Although the atoms were reflected somewhat specularly from the recording tracks on the tape, the cloud could not be focused because of diffuse reflection from the regions in between the tracks.…”
