The ground state of the Shor–Movassagh chain can be analytically described by the Motzkin
paths. There is no analytical description of the excited states. The model is not solvable. We …

We investigate various aspects of the integrability of the vertex models associated to the Dn2
affine Lie algebra with open boundaries. We first study the solutions of the corresponding …

A bstract We consider the integrable open-chain transfer matrix corresponding to a Y= 0
brane at one boundary, and a Y θ= 0 brane (rotated with the respect to the former by an …

Based on the finite-size analysis of the spectrum of the quantum group invariant deformation
of the OS p (3| 2) superspin chain we identify the operator content of the conformal field …

Integrable Kondo impurities in two cases of the one-dimensional tJ model are studied by
means of the boundary Z 2-graded quantum inverse scattering method. The boundary K …

We derive the Bethe ansatz equations on the half line for particles interacting through
factorized S-matrices invariant relative to the centrally extended su (2| 2) Lie superalgebra …
