Tunneling of ultracold atoms in time-independent potentials
Ennio Arimondo, Sandro Wimberger
We present theoretical as well as experimental results on resonantly enhanced quantum tunneling of Bose-Einstein condensates in optical lattices both in the linear case of single p…

Engineering of Landau-Zener tunneling
Ghazal Tayebirad, Riccardo Mannella, Sandro Wimberger
Several ways are discussed how to control the Landau-Zener tunneling in the Wannier-Stark system. We focus on a realization of this system with interacting and noninteracting ultra…
