Quantum dynamics of Bose-Einstein condensates in tilted and driven bichromatic optical lattices
D. Witthaut, F. Trimborn, V. Kegel +1
We study the dynamics of Bose-Einstein condensates in tilted and driven optical superlattices. For a bichromatic lattice, each Bloch band split up into two minibands such that the…

Nonlinear Landau-Zener tunneling in quantum phase space
F. Trimborn, D. Witthaut, V. Kegel +1
We present a detailed analysis of the Landau-Zener problem for an interacting Bose-Einstein condensate in a time-varying double-well trap, especially focussing on the relation betw…
