Simple Method to Calculate Percolation, Ising, and Potts Clusters: Renormalization-Group Applications
Constantino Tsallis, Silvio V. F. Levy
Abstract
We introduce a procedure which considerably simplifies the calculation of clusters like those commonly appearing in real-space renormalization-group treatments of bond-percolation and pure and random Ising and Potts problems. The method is illustrated through two applications for the $q$-state Potts ferromagnet.
