Supersymmetric boson localisation in speckle potentials — •Olivier Sigwarth and Cord Axel Müller — Physikalisches Institut, Universität Bayreuth, D-95440 Bayreuth

The coherent evolution of matter waves in disordered potentials is investigated using a supersymmetry approach. Starting from a microscopic characterisation of disordered speckle potentials and weakly interacting ultracold bosons, we develop a field-theoretic description of the localisation transition and evaluate its experimental realisability.
