Self-averaging and criticality: A comparative study in 2d random bond spin models
N G Fytas, A Malakis
We investigate and contrast, via the Wang-Landau (WL) algorithm, the effects of quenched bond randomness on the self-averaging properties of two Ising spin models in 2d. The random…
First-order transition features of the triangular Ising model with nearest- and next-nearest-neighbor antiferromagnetic interactions
A. Malakis, N. G. Fytas, P. Kalozoumis
We implement a new and accurate numerical entropic scheme to investigate the first-order transition features of the triangular Ising model with nearest-neighbor () and next…
Universal features and tail analysis of the order-parameter distribution of the two-dimensional Ising model: An entropic sampling Monte Carlo study
Anastasios Malakis, Nikolaos G. Fytas
We present a numerical study of the order-parameter probability density function (PDF) of the square Ising model for lattices with linear sizes . A recent efficient entro…
Quenched bond randomness in marginal and non-marginal Ising spin models in 2D
N G Fytas, A Malakis, I A Hadjiagapiou
We investigate and contrast, via entropic sampling based on the Wang-Landau algorithm, the effects of quenched bond randomness on the critical behavior of two Ising spin models in…
Monte-Carlo analysis of critical properties of the two-dimensional randomly site-diluted Ising model via Wang-Landau algorithm
I. A. Hadjiagapiou, A. Malakis, S. S. Martinos
The influence of random site dilution on the critical properties of the two-dimensional Ising model on a square lattice was explored by Monte Carlo simulations with the Wang-Landau…
Wang-Landau study of the random bond square Ising model with nearest- and next-nearest-neighbor interactions
N. G. Fytas, A. Malakis, I. Georgiou
We report results of a Wang-Landau study of the random bond square Ising model with nearest- () and next-nearest-neighbor () antiferromagnetic interactions. We con…
