A Monte Carlo study of leading order scaling corrections of phi^4 theory on a three dimensional lattice
Abstract
Description
We present a Monte Carlo study of the one-component $ϕ^4$ model on the cubic lattice in three dimensions. Leading order scaling corrections are studied using the finite size scaling method. We compute the corrections to scaling exponent $ω$ with high precision. We determine the value of the coupling $λ$ at which leading order corrections to scaling vanish. Using this result we obtain estimates for critical exponents that are more precise than those obtained with field theoretic methods.
