Cluster percolation and dynamical scaling in the Baxter--Wu model
Alexandros Vasilopoulos, Michail Akritidis, Nikolaos G. Fytas +1
We investigate the percolation behavior of Fortuin-Kasteleyn--type clusters in the spin- Baxter--Wu model with three-spin interactions on a triangular lattice. The considered…

Ordering transition of the three-dimensional four-state random-field Potts model
Manoj Kumar, Martin Weigel
Spin systems exposed to the influence of random magnetic fields are paradigmatic examples for studying the effect of quenched disorder on condensed-matter systems. In this context,…

Universal energy and magnetisation distributions in the Blume-Capel and Baxter-Wu models
A. R. S. Macedo, J. A. Plascak, A. Vasilopoulos +3
We analyse the probability distribution functions of the energy and magnetisation of the two-dimensional Blume-Capel and Baxter-Wu models with spin values in…
