Critical Behavior of a Three-State Potts Model on a Voronoi Lattice
We use the single-histogram technique to study the critical behavior of the three-state Potts model on a (random) Voronoi-Delaunay lattice with size ranging from 250 to 8000 sites. We consider the effect of an exponential decay of the interactions with the distance, J(r) = J0 exp(−ar), with a > 0, and observe that this system seems to have critical exponents γ and ν which are different from the...
متن کاملThree-state Potts model on a triangular lattice.
We study the phase diagram of the three-state Potts model on a triangular lattice with general interactions (ferro/antiferromagnetic) between nearest neighbor spins. When the interactions along two lattice-vector directions are antiferromagnetic and infinitely strong, this model becomes equivalent to a six-vertex model and exhibits a first-order (KDP) transition from an ordered phase into a cri...
متن کاملBoundary Critical Phenomena in the Three-State Potts Model
Boundary critical phenomena are studied in the 3State Potts model in 2 dimensions using conformal field theory, duality and renormalization group methods. A presumably complete set of boundary conditions is obtained using both fusion and orbifold methods. Besides the previously known free, fixed and mixed boundary conditions a new one is obtained. This illustrates the necessity of considering f...
متن کاملcritical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
15 صفحه اولOn the Three State Potts Model with Competing Interactions on the Bethe Lattice
In the present paper the three state Potts model with competing binary interactions (with couplings J and Jp) on the second order Bethe lattice is considered. The recurrent equations for the partition functions are derived. When Jp = 0, by means of a construction of a special class of limiting Gibbs measures, it is shown how these equations are related with the surface energy of the Hamiltonian...
