Driving defect modes of Bose-Einstein condensates in optical lattices
arXiv:cond-mat/0508503 · doi:10.1103/PhysRevLett.96.060403
Abstract
We present an approximate analytical theory and direct numerical computation of defect modes of a Bose-Einstein condensate loaded in an optical lattice and subject to an additional localized (defect) potential. Some of the modes are found to be remarkably stable and can be driven along the lattice by means of a defect moving following a step-like function defined by the period of Josephson oscillations and the macroscopic stability of the atoms.
