Disorder-induced splitting of a matter wavepacket in a two-component weakly interacting quantum gas

We theoretically investigate quantum transport of a two-component quantum gas in a disordered potential and predict a unique disorder-induced splitting of a matter wavepacket. We also demonstrate that the splitting of the mobile component originates from the inter-component interaction and the disordered potential on the localized component. © 2012 Chinese Optics Letters.
