Nature of problem:
The q-state Potts model (QPM) is related to many problems in statistical physics. This program may be used to calculate the spontaneous magnetization, the magnetic susceptibility, the internal energy, and the specific heat for the QPM.
The Swendsen and Wang's algorithm is used to simulate equilibrium bond configurations of the q-state bond-correlated percolation model (QBCPM) corresponding to the QPM. Based on the bond-configuration, the lattice sites are classified into different clusters via the multiple labeling technique of Hoshen and Kopelman. Hu's connection between the geometrical quantities of the QBCPM and the physical quantities of the QPM is used to calculate physical quantities of the QPM.
