Minimalistic real-space renormalization of Ising and Potts Models in two dimensions

Minimalistic real-space renormalization of Ising and Potts Models in two dimensions

We introduce and discuss a real-space renormalization group (RSRG) procedure on very small lattices, which in principle does not require any of the usual approximations, e.g. a cut-off in the expansion of the Hamiltonian in powers of the field. The procedure is carried out numerically on very small...
