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…

Transfer-matrix approach to the Blume-Capel model on the triangular lattice
Dimitrios Mataragkas, Alexandros Vasilopoulos, Nikolaos G. Fytas +1
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.…

Tricriticality and finite-size scaling in the triangular Blume-Capel ferromagnet
Dimitrios Mataragkas, Alexandros Vasilopoulos, Nikolaos G. Fytas +1
We report on numerical simulations of the two-dimensional spin- Blume-Capel ferromagnet embedded in a triangular lattice. Utilizing a range of Monte Carlo and finite-size scalin…
