Query: Mott-insulator state of cold atoms in tilted optical lattices: doublon
  dynamics and multi-level Landau-Zener tunneling   We discuss the dynamical response of strongly interacting Bose atoms in an
adiabatically tilted optical lattice. The analysis is performed in terms of the
multi-level Landau-Zenner tunneling. Different regimes of tunneling are
identified and analytical expressions for the doublon number, which is the
quantity measured in laboratory experiments, are derived.
