Effect of interactions on the localization of a Bose-Einstein condensate in a quasiperiodic lattice
Year: 2007
Type: article
Abstract: The transport properties of a Bose-Einstein condensate in a 1D incommensurate bichromatic lattice are investigated both theoretically and experimentally. We observe a blockage of the center of mass motion with low atom number, and a return of motion when the atom number is increased. Solutions of the Gross-Pitaevskii equation show how the localization due to the quasidisorder introduced by the incommensurate bichromatic lattice is affected by the interactions.
