Static versus dynamic universality in the site-diluted kagome Ising model
Alexandros Vasilopoulos, Zeynep Demir Vatansever, Erol Vatansever +2
We study the site-diluted Ising model on the kagome lattice using the Wolff single-cluster algorithm, focusing on both equilibrium and dynamic critical properties. The equilibrium…
First-order phase transitions in the three-dimensional Blume-Capel ferromagnet
D. Mataragkas, A. Vasilopoulos, Z. D. Vatansever +3
We investigate first-order phase transitions in the three-dimensional Blume-Capel ferromagnet on the simple cubic lattice by combining multicanonical simulations with two-parameter…
Cluster Dynamics Stay Fast-Until Tricriticality
Minjun Jeon, Alexandros Vasilopoulos, Dong-Hee Kim +2
Cluster Monte Carlo algorithms are widely regarded as the most effective route to overcoming critical slowing down in lattice spin systems. Whether this acceleration persists in th…
Crossover and universality breaking in the dilute Baxter-Wu model
Dimitrios Mataragkas, Alexandros Vasilopoulos, Dong-Hee Kim +1
The critical behavior of the Baxter-Wu model belongs to the universality class of the four-state Potts model. While the introduction of annealed vacancies does not alter the critic…
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…

We investigate the spin- Blume-Capel model on an infinite strip of the triangular lattice using the transfer-matrix method combined with a sparse-matrix factorization technique.…
Universal exotic dynamics in critical mesoscopic systems: Simulating the square root of Avogadro's number of spins
Mauro Bisson, Alexandros Vasilopoulos, Massimo Bernaschi +4
We explicitly demonstrate the universality of critical dynamics through unprecedented large-scale GPU-based simulations of two out-of-equilibrium processes, comparing the behavior…
