Anderson localization of a weakly interacting one dimensional Bose gas
T. Paul, M. Albert, P. Schlagheck +2
We consider the phase coherent transport of a quasi one-dimensional beam of Bose-Einstein condensed particles through a disordered potential of length L. Among the possible differe…
Coherent backscattering of Bose-Einstein condensates in two-dimensional disorder potentials
Michael Hartung, Thomas Wellens, Cord A. Mueller +2
We study quantum transport of an interacting Bose-Einstein condensate in a two-dimensional disorder potential. In the limit of vanishing atom-atom interaction, a sharp cone in the…
Nonlinear transport of Bose-Einstein condensates through mesoscopic waveguides
Tobias Paul, Michael Hartung, Klaus Richter +1
We study the coherent flow of interacting Bose-condensed atoms in mesoscopic waveguide geometries. Analytical and numerical methods, based on the mean-field description of the cond…
Superfluidity versus Anderson localization in a dilute Bose gas
T. Paul, P. Schlagheck, P. Leboeuf +1
We consider the motion of a quasi one dimensional beam of Bose-Einstein condensed particles in a disordered region of finite extent. Interaction effects lead to the appearance of t…
Effects of short-range interactions on transport through quantum point contacts: A numerical approach
Andreas Lassl, Peter Schlagheck, Klaus Richter
We study electronic transport through a quantum point contact, where the interaction between the electrons is approximated by a contact potential. Our numerical approach is based o…
Influence of classical resonances on chaotic tunnelling
Amaury Mouchet, Christopher Eltschka, Peter Schlagheck
Dynamical tunnelling between symmetry-related stable modes is studied in the periodically driven pendulum. We present strong evidence that the tunnelling process is governed by non…
