Ensemble dependence of the critical behavior of a system with long-range interaction and quenched randomness
Nir Schreiber, Reuven Cohen, Simi Haber
We propose a hybrid model governed by the Blume-Emery-Griffiths (BEG) Hamiltonian with a mean-field-like interaction, where the spins are randomly quenched such that some of them a…
Changeover phenomenon in randomly colored Potts models
Nir Schreiber, Reuven Cohen, Gideon Amir +1
A hybrid Potts model where a random concentration of the spins assume states and a random concentration of the spins assume states is introduced. It is know…
Unusual changeover in the transition nature of local-interaction Potts models
Nir Schreiber, Reuven Cohen, Simi Haber +2
A combinatorial approach is used to study the critical behavior of a -state Potts model with a round-the-face interaction. Using this approach it is shown that the model exhibit…
Ferromagnetic Potts models with multisite interaction
Nir Schreiber, Reuven Cohen, Simi Haber
We study the states Potts model with four site interaction on the square lattice. Based on the asymptotic behaviour of lattice animals, it is argued that when the sys…
Breaking of ergodicity and long relaxation times in systems with long-range interactions
D. Mukamel, S. Ruffo, N. Schreiber
The thermodynamic and dynamical properties of an Ising model with both short range and long range, mean field like, interactions are studied within the microcanonical ensemble. It…
Monte Carlo study of the Pure and Dilute Baxter-Wu model
Nir Schreiber, Joan Adler
We studied the pure and dilute Baxter-Wu (BW) models using the Wang-Landau (WL) sampling method to calculate the Density-Of-States (DOS). We first used the exact result for the DOS…
