Abstract. I will review several models that consist of one-dimensional loops living in the three-dimensional space. These models describe bosonic systems, and classical or quantum spin systems. Their common feature is that the joint distribution of their loop lengths has universal behaviour: It is always a Poisson-Dirichlet distribution. Most of this theory is conjectural, but it is backed by numerical studies and some partial rigorous results.
Best,
