摘要:We present a self consistent method based on cluster algorithms and Renormalization Group
on the lattice to study critical systems numerically. We illustrate it by means of the 2D Ising
model. We compute the critical exponents ν and η and the renormalization group flow of the
probability density function of the magnetization. The results, compared to the standard Monte
Carlo Renormalization Group proposed by Swendsen [1], are very accurate and the method works
faster by a factor which grows monotonically with the lattice size. This allows to simulate larger
lattices in reachable computational times.
