This paper studies a simple model of conductivity—a quantum particle (an atom) in a lattice, subject to a static field and interacting with the bath of Bose atoms. Results from direct numerical simulations of the system dynamics and statistical analysis of the eigenstates are compared with predictions from linear response theory, analytical solutions of the master equation, and the theory of quantum chaos. It is shown, in particular, that the behavior of the current–current correlation function… Expand

This paper studies the quantum dynamics of a charged particle in a two-dimensional square lattice, under the influence of electric and magnetic fields, and identifies the subspace of initial conditions ensuring directed transport with the drift velocity. Expand
Bose-Hubbard Hamiltonian: Quantum Chaos approach
We discuss applications of the theory of Quantum Chaos to one of the paradigm models of many-body quantum physics -- the Bose-Hubbard model, which describes, in particular, interacting ultracold BoseExpand

Collisionally induced transport in periodic potentials.
The transport of ultracold atoms in a tight optical lattice is investigated as a function of the collisional rate and a transition from a regime in which the mobility increases with increasing collisional rates to one in which it decreases is observed. Expand

Complexity in parametric bose-hubbard hamiltonians and structural analysis of eigenstates
We consider a family of chaotic Bose-Hubbard Hamiltonians parametrized by the coupling strength $k$ between neighboring sites. As $k$ increases the eigenstates undergo changes, reflected in theExpand
