"Bloch oscillations" in the Mott-insulator regime
Andrey R. Kolovsky
We study the dynamical response of cold interacting atoms in the Mott insulator phase to a static force. As shown in the experiment by M. Greiner et. al., Nature \textbf{415}, 39 (…

Interaction-induced decoherence of atomic Bloch oscillations
A. Buchleitner, A. R. Kolovsky
We show that the energy spectrum of the Bose-Hubbard model amended by a static field exhibits Wigner-Dyson level statistics. In itself a characteristic signature of quantum chaos,…

A new Bloch period for interacting cold atoms in 1D optical lattices
Andrey R. Kolovsky
The paper studies Bloch oscillations of ultracold atoms in optical lattice in the presence of atom-atom interaction. A new, interaction-induced Bloch period is identified. The anal…
