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…
The Physics of Local Optimization in Complex Disordered Systems
Mutian Shen, Gerardo Ortiz, Zhiqiao Dong +2
Limited resources motivate decomposing large-scale problems into smaller,``local" subsystems and stitching together the so-found solutions. We explore the physics underlying this a…
Cluster percolation in the three-dimensional random-bond Ising model
Lambert Münster, Martin Weigel
Based on extensive parallel-tempering Monte Carlo simulations, we investigate the relationship between cluster percolation and equilibrium ordering phenomena in the three-dimension…
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,…
