[en] We calculate the transport properties of an ultracold gas of Bose-
Einstein condensed atoms that is coupled from a magnetic trap into
a one-dimensional waveguide. A central aim of such guided atom
lasers is to study the role of atom-atom interaction in many-body
transport processes across finite scattering regions within the waveguide
resembling tunnel junctions and quantum dots. Our numerical
approach to solve this many-body scattering problem is based on a home-made
theory where the boundaries of the system are simulating an open system enabling
us to calulate observable in the steady-state regime such as density, current,
transmission. The results are compared to the mean-field regime.
