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…
Fate of the Ising universality class under nonreciprocal interactions
M. Akritidis, A. Garcés, A. Vasilopoulos +3
We study the critical behavior of a two-dimensional Ising model with nonreciprocal vision-cone interactions, which explicitly violate reciprocity and detailed balance. Extensive Mo…
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…
Competing ferromagnetic and antiferromagnetic phases on the frustrated Ising honeycomb lattice
Pietro F. Dias, Fabio M. Zimmer, Nikolaos G. Fytas +1
We investigate the frustrated -- Ising model on the honeycomb lattice, featuring first- and second-neighbor ferromagnetic couplings ( and ) and third-n…
