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…

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…
