GENERAL 8-VERTEX MODEL ON THE HONEYCOMB LATTICE: EQUIVALENCE WITH AN ISING MODEL

Ken‐Yu Lin, Fa Yueh Wu

Published Mar 10, 1990• 6 citations

Abstract

It is shown that the general 8-vertex model on the honeycomb lattice is always reducible to an Ising model in a nonzero but generally complex magnetic field. In the most general case of the staggered 8-vertex model characterized by 16 independent vertex weights, the equivalent Ising model has three anisotropic interactions and a staggered magnetic field which assumes two different values on the two sublattices.

ON RELATION BETWEEN SYMMETRIC VERTEX MODEL AND ISING MODEL ON THE SQUARE LATTICE

Ladislav Šamaj, M. Kolesík

The symmetric version of the two-state vertex model on the square lattice is studied. It is shown that there exists a manifold in the vertex weights parameter space on which the model can be mapped onto the Ising model in a field. The choices of symmetric vertex weights for which the equivalence holds in the whole temperature range are briefly discussed.

Eight-Vertex Model in Lattice Statistics and One-Dimensional Anisotropic Heisenberg Chain: II. Equivalence to a Generalized Ice-type Lattice Model

R. J. Baxter

Abstract We establish an equivalence between the zero-field eight-vertex model and an Ising model (with four-spin interaction) in which each spin has L possible values, labeled 1, …, L, and two adjacent spins must differ by one (to modulus L). Such an Ising model can also be thought of as a generalized ice-type model and we will later show that the eigenvectors of the transfer matrix can be obtained by a Bethe-type ansatz.

A free-fermion model, and the solution of an Ising model with pure triplet interactions

David W. Wood

A vertex model problem on the honeycomb lattice is reduced to an eight-vertex model problem which satisfies the free-fermion condition. An Ising model in which only triplet coupling terms are present on a decorated version of the triangular lattice is equivalent to this free-fermion model, thus providing an example of a pure three-spin interaction which has the conventional Ising-like logarithmic singularity in the specific heat, independently of the values of the coupling constants.

Staggered eight-vertex model

C.S. Hsue, Ken‐Yu Lin, Fa Yueh Wu

An eight-vertex model with staggered (site-dependent) vertex weights is considered. The model is an extension of the usual one with translationally invariant weights and contains sixteen independent vertex weights. From its Ising representation it is seen that there are actually only eleven independent parameters. After discussing some general symmetry properties of this model, we consider in detail the soluble case of a free-fermion model. We find that the staggered free-fermion model may exhibit up to three phase transitions. Generally the specific heat has logarithmic singularities, expect in some special cases it has an exponent $\ensuremath{\alpha}=\frac{1}{2}$ and the system is frozen below a unique transition point. Conditions for these special cases are given.

Staggered eight-vertex model with four sublattices

Ken‐Yu Lin, I P Wang

The staggered eight-vertex model on a square lattice which allows different vertex weights for the four sublattices of the square lattice has been studied. The soluble case of a free-fermion model is solved by the Pfaffian method. It is shown that the model may exhibit up to five phase transitions. In general the specific heat has logarithmic singularities, except in some special cases where the system exhibits first- or second-order phase transitions.

Critical frontier of the antiferromagnetic Ising model in a magnetic field: The honeycomb lattice

Fa Yueh Wu, X. N. Wu, Henk W. J. Blöte

A closed-form expression is proposed for the critical frontier, or the critical line, of the antiferromagnetic Ising model on the honeycomb lattice in a nonzero external magnetic field. We formulate the Ising model as an 8-vertex model and identify the critical frontier as a locus invariant under a generalized weak-graph transformation. In its simplest form the locus is an expression containing two unknown constants which we determine numerically. The resulting critical frontier lies very close to results of a finite-size analysis.
