Abstract

The two-point cluster function C2(r1, r2) provides a measure of clustering in continuum models of disordered many-particle systems and thus is a useful signature of the microstructure. For a two-phase disordered medium, C2(r1, r2) is defined to be the probability of finding two points at positions r1 and r2 in the same cluster of one of the phases. An exact analytical expression is found for the two-point cluster function C2(r1, r2) of a one-dimensional continuumpercolation model of Poisson-distributed rods (for an arbitrary number density) using renewal theory. We also give asymptotic formulas for the tail probabilities. Along the way we find exact results for other cluster statistics of this continuum percolation model, such as the cluster size distribution, mean number of clusters, and two-point blocking function.
