    • note
    • Note that U = 8t is widely accepted as the most physically meaningful value of Coulomb repulsion in these systems (see, for instance, [22]).

    • note
    • 2. Comparing the present numerical results with this energy gives a transition to the ferromagnetic solution approximately at U/t = 32, for the cluster sizes investigated here.

    • note
    • Note that, due to the delocalization of the polarons, the probability of finding the two holes in the same sublattice is of the same order as that of finding them in different sublattices (see fig. 1). This is in agreement with [22] (see also [25]).
