Transport dynamics of an interacting binary Bose–Einstein condensate in an incommensurate optical lattice

doi:10.1088/1674-1056/22/10/100501

Abstract We investigate the transport dynamics of an interacting binary Bose-Einstein condensate in an incommensurate optical lattice and predict a novel splitting of a matter wavepacket induced by disorder potential and inter–species interaction. The effect of atomic interaction on the dynamics of the mobile and localized atoms are also studied in detail. We also discuss the behavior of the balanced and inbalanced mixtures in the incommensurate optical lattice.

Keywords: multicomponent Bose–Einstein condensates Anderson localization dynamic properties
