Describing many-body bosonic waveguide scattering with the truncated Wigner method

Dujardin, Julien ; Engl, Thomas ; Urbina, Juan Diego ; Schlagheck, Peter


We consider quasi-stationary scattering of interacting bosonic matter waves in one-dimensional waveguides, as they arise in guided atom lasers. We show how the truncated Wigner (tW) method, which corresponds to the semiclassical description of the bosonic many-body system on the level of the diagonal approximation, can be utilized in order to describe such many-body bosonic scattering processes. ...
