Bose-Einstein condensates in accelerated double-periodic optical lattices: Coupling and Crossing of resonances
D. Witthaut, E. M. Graefe, S. Wimberger +1
We study the properties of coupled linear and nonlinear resonances. The fundamental phenomena and the level crossing scenarios are introduced for a nonlinear two-level system with…

Quantum transport and localization in biased periodic structures under bi- and polychromatic driving
A. Klumpp, D. Witthaut, H. J. Korsch
We consider the dynamics of a quantum particle in a one-dimensional periodic potential (lattice) under the action of a static and time-periodic field. The analysis is based on a ne…
