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…
Nonlinear Transport of Bose-Einstein Condensates Through Waveguides with Disorder
Tobias Paul, Patricio Leboeuf, Nicolas Pavloff +2
We study the coherent flow of a guided Bose-Einstein condensate incident over a disordered region of length L. We introduce a model of disordered potential that originates from mag…
Nonlinear Resonant Transport of Bose Einstein Condensates
Tobias Paul, Klaus Richter, Peter Schlagheck
The coherent flow of a Bose-Einstein condensate through a quantum dot in a magnetic waveguide is studied. By the numerical integration of the time-dependent Gross-Pitaevskii equati…
