Resonant tunneling of Bose-Einstein condensates in optical lattices
Alessandro Zenesini, Carlo Sias, Hans Lignier +7
In this article, we present theoretical as well as experimental results on resonantly enhanced tunneling of Bose-Einstein condensates in optical lattices both in the linear case an…
Engineered quantum tunnelling in extended periodic potentials
Sandro Wimberger, Donatella Ciampini, Oliver Morsch +2
Quantum tunnelling from a tilted, but otherwise periodic potential is studied. Our theoretical and experimental results show that, by controlling the system's parameters, we can en…
Many-body interband tunneling as a witness for complex dynamics in the Bose-Hubbard model
Andrea Tomadin, Riccardo Mannella, Sandro Wimberger
A perturbative model is studied for the tunneling of many-particle states from the ground band to the first excited energy band, mimicking Landau-Zener decay for ultracold, spinles…
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…
Resonant nonlinear quantum transport for a periodically kicked Bose condensate
Sandro Wimberger, Riccardo Mannella, Oliver Morsch +1
Our realistic numerical results show that the fundamental and higher-order quantum resonances of the delta-kicked rotor are observable in state-of-the-art experiments with a Bose c…
