Engineering of Landau-Zener tunneling
arXiv:1010.1671 · doi:10.1007/s00340-011-4430-6
Abstract
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 ultracold bosons. The tunneling from the ground band to the continuum is shown to depend crucially on the initial condition and system parameters and, more interestingly, on added timedependent disorder -- noise -- on the lattice beams.
