For instance, the average cluster size in the Wolff algorithm is often said to be an estimator for the magnetic -susceptibility in the Ising, Potts, and $\mathrm O(n)$ models, but really what +susceptibility in the Ising, Potts, and (with clusters weighted by the +components of their spins along the reflection direction +\cite{hasenbusch_improved_1990}) $\mathrm O(n)$ models, but really what it estimates is the averaged squared magnetization, which corresponds to the susceptibility when the average magnetization is zero. At finite field the latter thing is no longer true, but the correspondence between cluster size |
