Boundary K-matrices for the six vertex and the n(2n-1)An-1vertex models

Abstract

Boundary conditions compatible with integrability are obtained for two-dimensional models by solving the factorizability equations for the reflection matrices K +or- ( theta ). For the six vertex model the general solution depending on four arbitrary parameters is found. For the A n-1 models all diagonal solutions are found. The associated integrable magnetic Hamiltonians are explicitly derived.

Boundary K-matrices for the XYZ, XXZ and XXX spin chains

Hector J. de Vega, A Gonzalez-Ruiz

The general solutions for the factorization equations of the reflection matrices K +or- ( theta ) for the eight-vertex and six-vertex models (XYZ, XXZ and XXX chains) are found. The associated integrable magnetic Hamiltonians are derived explicitly, finding families depending on several continuous as well as discrete parameters.

General Yang-Baxterization of reflection equations and general K-matrices of An-1vertex models

Hong‐Chen Fu, Mo‐Lin Ge

General Yang-Baxterization of reflection equations for R with two distinct eigenvalues is presented. This procedure is used to construct reflection K-matrices of reflection equations for the A n-1 vertex models. (Diagonal) K-matrices by de Vege and Gonzalez-Ruiz(1993) for the A n-1 vertex model are reproduced. Furthermore, some new off-diagonal K-matrices for the A n-1 vertex model are obtained.

Algebraic Bethe Ansatz Solution to C N Vertex Model with Open Boundary Conditions

Guang-Liang Li, Kangjie Shi, Rui‐Hong Yue

We present three diagonal reflecting matrices for the C N vertex model with open boundary conditions and exactly solve the model by using the algebraic Bethe ansatz. The eigenvector is constructed and the eigenvalue and the associated Bethe equations are achieved. All the unwanted terms are cancelled out by three kinds of identities.

Reflection matrices for theUq[spo(2n|2m)] vertex model

A Lima-Santos

We propose a classification of the solutions of the graded reflection equations for the U q [ spo (2 n |2 m )] vertex model. We find twelve distinct classes of reflection matrices such that four of them are diagonal. In the non-diagonal matrices the number of free parameters depends on the number of bosonic (2 n ) and fermionic (2 m ) degrees of freedom while in the diagonal ones we find solutions with at most one free parameter.
