A Variational Approach to Monte Carlo Renormalization Group
arXiv:1707.08683 · doi:10.1103/PhysRevLett.119.220602
Abstract
We present a Monte Carlo method for computing the renormalized coupling constants and the critical exponents within renormalization theory. The scheme, which derives from a variational principle, overcomes critical slowing down, by means of a bias potential that renders the coarse grained variables uncorrelated. The 2D Ising model is used to illustrate the method.
