Monte Carlo renormalization-group analysis of the lattice phi(4) model in D=3,4

We present a simple, sophisticated method to capture renormalization-group flow in Monte Carlo simulation, which provides important information of cri tical phenomena. We applied the method to the D = 3,4 lattice phi(4) model and obtained a renormalization flow diagram that well reproduces theoretica lly predicted behavior of the continuum phi(4) model. We also show that the method can be easily applied to much moro complicated models, such as frus trated spin models.
