We consider lattice models of quantum spins that can be represented by random loop models in one more dimensions. Such models have been introduced over the years by Ginibre, Conlon-Solovej, Toth, and Aizenman-Nachtergaele. Long-range correlations are given by loops of macroscopic lengths. We argue that their joint distribution is given by the Poisson-Dirichlet distribution for random partitions. I will review some results that support this conjecture, results that come from either rigorous statistical mechanics, or from probability theory. This is joint work with C. Goldschmidt and P. Windridge.
