15. In isotropic self-focusing media, the force between mutually incoherent solitons is only attractive. In photorefractive media, an incoherent collision between screening solitons is primarily attractive (and leads to the results shown in Ref. 10), except in the pathologic case when such two-dimensional solitons collide at a shallow angle and when the plane formed by the collision trajectories is parallel to the c axis (direction of the applied field). In this case one can observe some small anomalous repulsion, as observed by W. Krolikowski, M. Saffman, B. Luther-Davies, and C. Denz, Phys. Rev. Lett. 80, 3240 (1998). We believe that it is possible to utilize this anomalous interaction to bring two solitons (at those special conditions) to a proximity closer than what we have demonstrated.
