Quantum walks and quantum simulations with Bloch oscillating spinor atoms
D. Witthaut
We propose a scheme for the realization of a quantum walker and a quantum simulator for the Dirac equation with ultracold spinor atoms in driven optical lattices. A precise control…

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…
