Surprising convergence of the Monte Carlo renormalization group for the three-dimensional Ising model
Dorit Ron, Achi Brandt, Robert H. Swendsen
We present a surprisingly simple approach to high-accuracy calculations of the critical properties of the three-dimensional Ising model. The method uses a modified block-spin transformation with a tunable parameter to improve convergence in the Monte Carlo renormalization group. The block-spin parameter must be tuned differently for different exponents to produce optimal convergence.
