Glassiness and dynamic arrest in magnetic and non-magnetic colloids
Anuj Kumar Singh, Lambert Münster, Martin Weigel +1
We investigate and compare a range of indicators for glassiness in monodisperse magnetic and non-magnetic soft-sphere fluids at low temperatures with a view to exploring the effect…
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…
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…
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…
Spin glasses and percolation
Lambert Münster, Martin Weigel
The description of thermodynamic phase transitions in terms of percolation transitions of suitably defined clusters has a long tradition and boasts a number of important successes,…
The Griffiths phase and beyond: A large deviations study of the magnetic susceptibility of the two-dimensional bond-diluted Ising model
Lambert Münster, Alexander K. Hartmann, Martin Weigel
The Griffiths phase in systems with quenched disorder occurs below the ordering transition of the pure system down to the ordering transition of the actual disordered system. While…
Optimized population Monte Carlo
P. L. Ebert, D. Gessert, W. Janke +1
Population Monte Carlo simulations in the form commonly referred to as population annealing can serve as a useful meta-algorithm for simulating systems with complex free-energy lan…
Optimized GPU simulation of continuous-spin glass models
Taras Yavors'kii, Martin Weigel
We develop a highly optimized code for simulating the Edwards-Anderson Heisenberg model on graphics processing units (GPUs). Using a number of computational tricks such as tiling,…
