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…
Separatrix chaos: new approach to the theoretical treatment
S. M. Soskin, R. Mannella, O. M. Yevtushenko
We develop a new approach to the theoretical treatment of the separatrix chaos, using a special analysis of the separatrix map. The approach allows us to describe boundaries of the…
Many-body Landau-Zener tunneling in the Bose-Hubbard model
Andrea Tomadin, Riccardo Mannella, Sandro Wimberger
We study a model for ultracold, spinless atoms in quasi-one dimensional optical lattices and subjected to a tunable tilting force. Statistical tests are employed to quantitatively…
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…
