Criticality of the random-site Ising model: Metropolis, Swendsen-Wang and Wolff Monte Carlo algorithms
We apply numerical simulations to study of the criticality of the 3D Ising model with random site quenched dilution. The emphasis is given to the issues not being discussed in detail before. In particular, we attempt a comparison of different Monte Carlo techniques, discussing regions of their a...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | We apply numerical simulations to study of the criticality of the 3D Ising
model with random site quenched dilution. The emphasis is given to
the issues not being discussed in detail before. In particular, we attempt
a comparison of different Monte Carlo techniques, discussing regions of
their applicability and advantages/disadvantages depending on the aim of
a particular simulation set. Moreover, besides evaluation of the critical indices
we estimate the universal ratio Γ⁺/Γ⁻ for the magnetic susceptibility
critical amplitudes. Our estimate Γ⁺/Γ⁻− = 1.67±0.15 is in a good agreement
with the recent MC analysis of the random-bond Ising model giving
further support that both random-site and random-bond dilutions lead to
the same universality class. |
