Coherent transport
C. R. Acad. Sci. (Paris), Série IV 2 (2001) 573-80, proceedings of the `Euroconference on Atom Optics and Interferometry' (Cargese, France 26-29 july 2000).


    We discuss the transport of matter waves in low-dimensional waveguides. Due to scattering from uncontrollable noise fields, the spatial coherence gets reduced and eventually lost. We develop a description of this decoherence process in terms of transport equations for the atomic Wigner function. We outline its derivation and discuss the special case of white noise where an analytical solution can be found.
