Abstract
We study the effect of coherent propagation of two interacting particl es in an effective 2-3-d disordered potential. Our numerical data demo nstrate that in dimension d > 2, interaction can lead to two-particles delocalization below one-particle delocalization border. We also find that the distance between the two delocalized particles (pair size) g rows logarithmically with time. As a result pair propagation is subdif fusive.
