Wang - Landau algorithmIsing modelWe introduce a simple method to compute free energy differences employing Jarzynski identity in conjunction with Wang - Landau algorithm. We demonstrate this method on Ising spin system by comparing the results with those obtained from canonical sampling....

INTRODUCTIONThe Wang-Landau (WL) algorithm [1–3] has been provenuseful in solving a wide range of computational problemsin statistical physics, including spin-glass mode...
We present a modified Wang-Landau algorithm for models with continuous degrees of freedom. We demonstrate this algorithm with the calculation of the joint density of states of ferromagnet Heisenberg models and a model polymer chain. The joint density of states contains more information than the densi...

C Gervais,T Wüst,DP Landau,Y Xu 摘要: A two-step Monte Carlo procedure is developed to investigate the dimerization process of the homodimer glycophorin A. In the first step, the energy density of states of the system is estimated by the Wang–Landau algorithm. In the second step, a ...
Results: A non-Boltzmannian Monte Carlo algorithm was designed by Wang and Landau to estimate the density of states for complex systems, such as the Ising model, that exhibit a phase transition. In this article, we apply the Wang-Landau (WL) method to compute the density of states for sec...
The model is studied in both its first- and second-order phase transition regime for several values of the crystal field via a sophisticated two-stage numerical strategy using the Wang-Landau algorithm. Using classical finite-size scaling techniques we estimate with high accuracy phase-transition ...
