For simplicity, we will consider the Ising version of this model. Ising spins take two values, <math>\sigma_i = \pm 1</math>, and are located on a lattice with <math>N</math> sites, indexed by <math>i = 1, 2, \ldots, N</math>. The energy of the system is expressed as a sum over nearest neighbors <math>\langle i, j \rangle</math>: <center><math> E = - \sum_{\langle i, j \ran...")
