Abstract (English)

We numerically study time-dependent quantum transport of an interacting Bose-Einstein condensate based on the Gross-Pitaevskii equation in a two-dimensional correlated disorder potential. The scattering- and transport mean-free-path is numerically calculated and compared with a diagrammatic approach. Furthermore we introduce the phenomenon of coherent backscattering in the context of ...

Wir untersuchen mit numerischen Methoden den zeit-abhängigen Quantentransport eines Wechselwirkenden Bose-Einstein Kondensats auf Basis der Gross-Pitaevskii Gleichung in einem zwei-dimensionalen korrelierten Unordnungspotential. Die mittlere freie Streu- und Transportweglänge wird numerisch berechnet und mit einer diagrammatischen Methode verglichen. Desweiteren führen wir das Phänomen der ...
