Nonlinearity induced destruction of resonant tunneling in the Wannier-Stark problem
Sandro Wimberger, Riccardo Mannella, Oliver Morsch +3
We present detailed numerical results on the dynamics of a Bose-Einstein condensate in a tilted periodic optical lattice over many Bloch periods. We show that an increasing atom-at…

Dynamical instability, Chaos, and Bloch oscillations of Bose-Einstein condensates in tilted optical lattices
Andrey R. Kolovsky
We study the Bloch dynamics of a Bose-Einstein condensate of cold atoms by using the formalism of the discrete nonlinear Schroedinger equation. Depending on the static force magnit…

Emergence of superfluid transport in a dynamical system of ultracold atoms
Joachim Brand, Andrey R. Kolovsky
The dynamics of a Bose-Einstein condensate is studied theoretically in a combined periodic plus harmonic external potential. Different dynamical regimes of stable and unstable coll…
