A new Bloch period for interacting cold atoms in 1D optical lattices
arXiv:cond-mat/0302092 · doi:10.1103/PhysRevLett.90.213002
Abstract
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 analytical results are corroborated by realistic numerical calculations.
