The latter can be used, at least in principle, to express more general boundary. Uses the spin 1/2 XXZ chain and the six-vertex model as examples, and discusses the Yang-Baxter equation, corner transfer matrices, vertex operators, and the Frenkel. Its origins go back to the Pauling ice model 1 and it was later employed in the description of a two-dimensional ferroelectric (for a review see 2). As a motivating example, we will prove in Section 4 one of the simplest such associations, between the trace of VM and the partition function of the six-vertex model. Here six vertex model solvable pdf we discuss the “commuting transfer matrix” T,Qequations for these models, writing them in a more explicit and transparent notation that we believe offers new insights. A vertex model is a type of statistical mechanics model in which the Boltzmann weights are associated with a vertex in the model (representing an six vertex model solvable pdf atom pdf or particle).

correlation functionsofthedomain wall six-vertex model. Variants have been proposed as six vertex model solvable pdf models of certain ferroelectric and antiferroelectric crystals. As an application, we show that with boundary con-ditions corresponding to integer partitions λ, the six-vertex model is exactly solvable.

Let us consider a lattice (or sometimes more general graph) in which the edges are labeled six vertex model solvable pdf with &92;spins". Six-vertex con gurations have a height six vertex model solvable pdf function which. The six-vertex modelwas solved by Lieb and Sutherland in the 1960’s, then solved another way by Baxter whose method extended to theeight.

In that case we have a()λλ:=+ η, b()λλ:= and c()λη:=. Surveys recent development on the interplay between solvable lattice models in statistical mechanics and representation theory of quantum affine algebras. The exact solution in three dimensions is only know.

Solvable Lattice Models In these examples, the state of a model is described by specifying the values of parameters associated with the vertices or edges of a planar graph. We six vertex model solvable pdf also introduce various exactly solvable models defined on two-dimensional lattices such as the chiral Potts model and the IRF models. We introduce and solve a special family of integrable interacting vertex models that generalizes the well known six-vertex six vertex model solvable pdf model. . six-vertex model on a domain D, with fixed density of lines ρ 1 for the horizontal bonds and fixed density of lines ρ 2 for the vertical bonds on the boundary, are identical each other in the thermodynamic limit: f = f(ρ 1,ρ 2). vertex-face correspondence works on levelthe of vertex operators and bosonization, it making possibleto six vertex model solvable pdf express the correlationfunctions of the eight-vertex model in termsthe free of field representation aimed todescribe the six vertex model solvable pdf SOSmodel. Fractal structure of the six-vertex model is introduced with the use of the IFS (Iterated Function Systems). The free energy per site in the thermodynamic.

This contrasts with a nearest-neighbour model, such as the Ising model, in which the energy, and thus the Boltzmann weight of a statistical microstate is attributed to the bonds connecting two neighbouring particles. &92;’ Sincewe shall speak about some models. Kohei Motegi, Two point functions for the six vertex model with reflecting end, arXiv:1006. • The six-vertex model was solved by Lieb, Sutherland and Baxter in the 1960’s. The first such example was the 2-dimensional Ising model (Onsager 1944).

The approach manifests the relationship between the six-vertex six vertex model solvable pdf and chiral Potts models, and between the six vertex model solvable pdf eight-vertex. Lieb found the exact solution to a two-dimensional ice model known as "square ice". We can readily see that =a b + c which corresponds to a quotient of the six-vertex model alge-braic curve a22+−bc 2 =∆ ab with ∆ = 2. six-vertex model. .

The parameter is usually refereed to η. · the diagonal-to-diagonal six-vertex model being known to be solvable for quite a long time 34, to our knowledge the spectral gap for this model with Boltzmann weights associated to stochastic. The 6-vertex model is integrable: there is a uniparamet-ric family of transfer matrices T(u) commuting among themselves. classical analog, the six-vertex model), and the 2d classical rotor or &92;XY" model. We discuss the connection of the six-vertex model to the conformal field theory with c=1.

THE six vertex model solvable pdf YANG-BAXTER EQUATION The partition function of pdf the six-vertex model was rst computed in the restricted case with x= y= zby Lieb 2, using the Bethe ansatz to diagonalize the six vertex model solvable pdf transfer six vertex model solvable pdf matrix. In the process, we introduce new symmetric functions termed metaplectic symmetric functions and explain how pdf they are related to Whittaker functions. To our knowledge, the six vertex model six vertex model solvable pdf and its higher spin descen-dants 10, 11 are the only solvable vertex systems analyzed so far with non-diagonal boundary conditions. The associated row-to-row transfer matrices are diagonalized by using six vertex model solvable pdf the recently introduced matrix. Later, Baxter six vertex model solvable pdf solved a generalization of pdf the six-vertex model 4 using what is now known as the Yang-Baxter relation. (including the uniform spanning tree and the Ising model) that have independently solvable random lattice analogs; these analogs are described in 21, six vertex model solvable pdf along with connections to Liouville quantum gravity and string theory. model as a free-fermion six-vertex model and solving the associated inversion identity 7,5,28 satisfied by the transfer matrices.

1 The six-vertex model We review the six-vertex model from statistical mechanics. In addition to six vertex model solvable pdf the usual nearest neighbour interactions among the vertices, there exist extra hard-core interactions among pairs of vertices at. We propose the new family of six vertex model solvable pdf the exactly solvable discrete state BCS - type Hamiltonians based on its relationship to the six-vertex model in the quasiclassical limit both in the rational and the.

As with the ice-type models, the eight-vertex model is a square lattice model, where each state is a configuration of six vertex model solvable pdf arrows at a vertex. A six-vertex dircteed athp ensemble is a family up-right directed paths in the non-negative quadrant Z2 >0, such that each path emanates from either the x-axis or y-axis, and such that no two paths share an edge (although they may share vertices); see Figure 1.

TENSOR PRODUCT VERTEX ANSATZS. There is clearly a mismatch between the definitions of exact solvability in the two.

Lee and Yang added, is equivalent to Baxter’s symmetric eight-vertex model and six vertex model solvable pdf hence solvable. We reproduce the boundary 1-point function determinant expression of Bogoliubov, Pronko and Zvonarev, then use that as a building block to obtain analogous expressions for boundary 2-point functions. 3 The thermodynamic limit 194 9. The XXZ model is a deformation of the Heisenberg model breaking the SU(2) symmetry down to a U(1) pdf subgroup.

In 1967, Elliott H. 1 The Bethe hypothesis 203 10. weight a b c η α β ξTable 1. 4 Various results on the critical exponents 199 10 Identical particles with δ-interactions 203 10. This has recently been generalized by Huang, Wu, Kunz and Kim to the case where the We also write this matrix by M (a, x, b, y, six vertex model solvable pdf c, z).

When a = x, b = y and c = z, we abridge it as six vertex model solvable pdf M (a, b, c). where V is the the transfer matrix of the six-vertex model on a finite square lattice with.
