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…
Nonequilibrium excitations of molecular vibrons
D. A. Ryndyk, M. Hartung, G. Cuniberti
We consider the nonequilibrium quantum vibrations of a molecule clamped between two macroscopic leads in a current-carrying state at finite voltages. Our approach is based on the n…
Hybridization of electron subbands in a double quantum well at quantizing magnetic field
V. T. Dolgopolov, A. A. Shashkin, E. V. Deviatov +5
We employ magnetocapacitance and far-infrared spectroscopy techniques to study the spectrum of the double-layer electron system in a parabolic quantum well with a narrow tunnel bar…
