Critical aspects of three-dimensional anisotropic spin-glass models
T. Papakonstantinou, N. G. Fytas, A. Malakis +1
We study the three-dimensional Ising model with a longitudinal anisotropic bond randomness on the simple cubic lattice. The random exchange interaction is applied only in t…
A comparative study of selected parallel tempering methods
A. Malakis, T. Papakonstantinou
We review several parallel tempering schemes and examine their main ingredients for accuracy and efficiency. The present study covers two selection methods of temperatures and seve…
Critical Behavior of the Three-Dimensional Ising model with Anisotropic Bond Randomness at the Ferromagnetic-Paramagnetic Transition Line
T. Papakonstantinou, A. Malakis
We study the three-dimensional Ising model with a spatially uniaxially anisotropic bond randomness on the simple cubic lattice. The random exchange is applied in th…
Universality of the Ising and the S=1 model on Archimedean lattices: A Monte Carlo determination
A. Malakis, G. Gulpinar, Y. Karaaslan +2
The Ising model S=1/2 and the S=1 model are studied by efficient Monte Carlo schemes on the (3,4,6,4) and the (3,3,3,3,6) Archimedean lattices. The algorithms used, a hybrid Metrop…
Universality aspects of the d=3 random-bond Blume-Capel model
A. Malakis, A. Nihat Berker, N. G. Fytas +1
The effects of bond randomness on the universality aspects of the simple cubic lattice ferromagnetic Blume-Capel model are discussed. The system is studied numerically in both its…
Multicritical Points and Crossover Mediating the Strong Violation of Universality: Wang-Landau Determinations in the Random-Bond Blume-Capel model
A. Malakis, A. Nihat Berker, I. A. Hadjiagapiou +2
The effects of bond randomness on the phase diagram and critical behavior of the square lattice ferromagnetic Blume-Capel model are discussed. The system is studied in both the pur…
