Monte Carlo Renormalization Group Analysis of Lattice ϕ4 Model in D=3,4
M. Itakura
Abstract
We present a simple, sophisticated method to capture renormalization group flow in Monte Carlo simulation, which provides important information of critical phenomena. We applied the method to D=3,4 lattice ϕ4 model and obtained renormalization flow diagram which well reproduces theoretically predicted behavior of continuum ϕ4 model. We also show that the method can be easily applied to much more complicated models, such as frustrated spin models.
