Ising exponents in the two-dimensional site-diluted Ising model

TL;DR

This paper investigates the critical exponents of the two-dimensional site-diluted Ising model using Monte Carlo simulations, revealing deviations from pure Ising exponents that are explained by logarithmic corrections, maintaining the same universality class.

Contribution

It demonstrates that deviations in critical exponents are due to logarithmic corrections, not a change in the universality class, in the 2D site-diluted Ising model.

Findings

Critical exponents deviate from pure Ising values

Logarithmic corrections explain the deviations

Universality class remains unchanged

Abstract

We study the site-diluted Ising model in two dimensions with Monte Carlo simulations. Using finite-size scaling techniques we compute the critical exponents observing deviations from the pure Ising ones. The differences can be explained as the effects of logarithmic corrections, without requiring to change the Universality Class.
