The basic laws governing atoms and electrons are well understood, but it is impossible to make predictions about the behaviour of large systems of condensed matter. A common approach is to introduce simple models and to use notions of statistical mechanics. I will review certain quantum spin systems such as the Heisenberg model. As it turns out, they can be represented by models of random permutations and of random loops.
