Jc. Earnshaw et Dj. Robinson, SCALE-INVARIANCE IN 2-DIMENSIONAL REACTION-LIMITED COLLOIDAL AGGREGATION, Journal of physics. Condensed matter, 7(30), 1995, pp. 397-403
Experimental studies of reaction-limited cluster-cluster aggregation i
n dense colloidal monolayers at liquid surfaces demonstrate that the s
ystem evolves to a state lacking any characteristic length scale. In p
articular, the structure function S(q, t) diverges in the limit t -->
infinity and q --> 0, suggestive of self-organized criticality. The se
lf-organization is reflected in the cooperative nature of the divergen
ce.
