Relaxation properties in a diffusive model of extended objects on a triangular lattice

Šćepanović, J.R.; Budinski-Petković, Lj.; … - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 5, pp. 1153-1163

-mers on the planar triangular lattice. Among other features of this system, we observed that the suppression of rotational …-avoiding random walks on a triangular lattice. We start by studying the percolation properties of random sequential adsorption of … extended objects on a triangular lattice. We find that for various objects of the same length, the threshold ρp∗ of more …

Vortex generation in the RSP game on the triangular lattice

Nishiuchi, Hiroyuki; Hatano, Naomichi; Kubo, Kenn - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 5, pp. 1319-1337

with the maximum point. The model exhibits a steady pattern with pairs of vortices and sinks on the triangular lattice. It … is shown that the stationary vortex is due to the frustrations on the triangular lattice. A frustration is the three …

Baxter–Wu model with fixed magnetization

Martinos, S.S.; Malakis, A.; Hadjiagapiou, I. - In: Physica A: Statistical Mechanics and its Applications 366 (2006) C, pp. 273-280

We study Baxter–Wu triangular model with fixed magnetization in the framework of canonical and microcanonical ensemble, constructing the density of states by Wang–Landau algorithm. We use an approximation similar to a recently developed scheme (critical minimum energy subspace). In this...

Finite-size scaling analysis of the critical behavior of the Baxter–Wu model

Martinos, S.S.; Malakis, A.; Hadjiagapiou, I. - In: Physica A: Statistical Mechanics and its Applications 352 (2005) 2, pp. 447-458

We use the recently developed critical minimum energy subspace (CrMES) approximation scheme to study the critical behavior of the Baxter–Wu model. This scheme uses only a properly determined part of the energy spectrum and allows us to obtain high accuracy for relatively large systems with...

Finite-size scaling at first- and second-order phase transitions of Baxter–Wu model

Martinos, S.S.; Malakis, A.; Hadjiagapiou, I. - In: Physica A: Statistical Mechanics and its Applications 355 (2005) 2, pp. 393-407

Using a finite-size phenomenological theory we investigate the behavior of the Baxter–Wu model for both first- and second-order transitions. In order to distinguish between the two kinds of transition we study the finite-size scaling behavior of the order parameter and the susceptibility of...
