Andrey R. Kolovsky. Mott-insulator state of cold atoms in tilted optical lattices: Doublon dynamics and multilevel Landau-Zener tunneling [Текст] / Andrey R. Kolovsky, Dmitrii N. Maksimov // PHYSICAL REVIEW A. — 2016. — Т. 94 (№ 4). — С. 043630-p1-043630-p9Abstract:
We discuss the dynamical response of strongly interacting Bose atoms in an adiabatically tilted optical lattice. The analysis is performed in terms of the multilevel Landau-Zener tunneling. Different regimes of tunneling are identified and analytical expressions for the doublon number, which is the quantity measured in laboratory experiments, are derived.
