Título: "Interacting bosons in random media: superfluidity versus Anderson
localization"

Abstract:
We consider the general transport properties of Bose-Einstein condensed
particles ("atom lasers") relative to a scattering potential. Several
recent experimental results are discussed. In the particular case of a
disordered medium, we show that interaction effects lead to two distinct
stationary flows. One is subsonic and corresponds to superfluid motion.
The other one is supersonic, and shows Anderson localization, with a
localization length renormalized by interactions. The existence of
dissipative "turbulent" phases is also described.
