Cluster Percolation in the Two-Dimensional Ising Spin Glass
Lambert Münster, Martin Weigel
Suitable cluster definitions have allowed researchers to describe many ordering transitions in spin systems as geometric phenomena related to percolation. For spin glasses and some…
Weighted averages in population annealing: analysis and general framework
Paul L. Ebert, Denis Gessert, Martin Weigel
Population annealing is a powerful sequential Monte Carlo algorithm designed to study the equilibrium behavior of general systems in statistical physics through massive parallelism…
Universality in the two-dimensional dilute Baxter-Wu model
Alexandros Vasilopoulos, Nikolaos G. Fytas, Erol Vatansever +2
We study the question of universality in the two-dimensional spin- Baxter-Wu model in the presence of a crystal field . We employ extensive numerical simulations of two types…
Critical behavior of the three-state random-field Potts model in three dimensions
Manoj Kumar, Varsha Banerjee, Sanjay Puri +1
Enormous advances have been made in the past 20 years in our understanding of the random-field Ising model, and there is now consensus on many aspects of its behavior at least in t…
Quasi-exact ground-state algorithm for the random-field Potts model
Manoj Kumar, Martin Weigel
The use of combinatorial optimization algorithms has contributed substantially to the major progress that has occurred in recent years in the understanding of the physics of disord…
Multicanonical simulations of the 2D spin- Baxter-Wu model in a crystal field
Nikolaos G. Fytas, Alexandros Vasilopoulos, Erol Vatansever +2
We investigate aspects of universality in the two-dimensional (2D) spin- Baxter-Wu model in a crystal field using a parallel version of the multicanonical algorithm employed…
