Reflection matrices for theUq[osp(r|2m)(1)] vertex model

Abstract

The graded reflection equation is investigated for the U q [ osp ( r |2 m ) (1) ] vertex model. We have found diagonal solutions with at the most one free parameter and non-diagonal solutions with the number of free parameters depending on the number of bosonic ( r ) and fermionic (2 m ) degrees of freedom.

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.

Reflection matrices for theUq[sl(m|n)(1)] vertex model

A. Lima-Santos

We investigate the possible regular solutions of the boundary Yang–Baxter equation for the vertex models associated with the graded version of the A n −1 (1) affine Lie algebra, the U q [ sl ( m | n ) (1) ] vertex model, also known as the Perk–Schultz model.

Fermionic reflection matrices

Nikos Karaiskos

We consider the insertion of integrable boundaries for a class of supersymmetric quantum models. The generic conditions for constructing purely bosonic, purely fermionic or mixed type solutions of the graded reflection equation are extracted. Focusing on models associated with g l ( m | n ) or 𝒰 q ( g l ( m | n )) symmetry, we first consider purely bosonic reflection matrices with special structures, for general values of m , n . These solutions provide the bosonic parts to construct fuller reflection matrices, containing fermionic degrees of freedom as well.

Exact Solution for the Osp (1|2 n ) Vertex Model under Open Boundary Conditions

Guang-Liang Li

We exactly solve the Osp (1|2 n ) vertex model with two different diagonal reflecting matrices with the nested Bethe ansatz method. It is shown that our results agree with that obtained by analytical Bethe ansatz method.

Free fermionic elliptic reflection matrices and quantum group invariance

Rodolfo Cuerno, A Gonzalez-Ruiz

Diagonal solutions for the reflection matrices associated to the elliptic R matrix of the eight-vertex free fermion model are presented. They lead through the second derivative of the open chain transfer matrix to an XY Hamiltonian in a magnetic field which is invariant under a quantum deformed Clifford-Hopf algebra.
