This force, which can be generated by an intense laser field at a wavelength longer than that of the lattice-generating laser, is shown to bind pairs of cold atoms trapped at different lattice sites, and cause their translational quantum correlations (spatial entanglement).Extended to 3D calculations, experimental possibility discussed; 6 pages including 3 figures, RevtexQuantum PhysicsCondensed Mattertext
