Bloch oscillations of Bose-Einstein condensates: Breakdown and revival
D. Witthaut, M. Werder, S. Mossmann +1
We investigate the dynamics of Bose-Einstein condensates (BEC) in a tilted one-dimensional periodic lattice within the mean-field (Gross-Pitaevskii) description. Unlike in the line…
Bound and resonance states of the nonlinear Schroedinger equation in simple model systems
D. Witthaut, S. Mossmann, H. J. Korsch
The stationary nonlinear Schroedinger equation, or Gross-Pitaevskii equation, is studied for the cases of a single delta potential and a delta-shell potential. These model systems…
Two-dimensional Bloch oscillations: A Lie-algebraic approach
S. Mossmann, A. Schulze, D. Witthaut +1
A Lie-algebraic approach successfully used to describe one-dimensional Bloch oscillations in a tight-binding approximation is extended to two dimensions. This extension has the sam…
Bloch oscillations of cold atoms in optical lattices
Andrey R. Kolovsky, Hans Jürgen Korsch
This work is devoted to Bloch oscillations (BO) of cold neutral atoms in optical lattices. After a general introduction to the phenomenon of BO and its realization in optical latti…
