Exact solution of the quantum integrable model associated with the Motzkin spin chain

open access: yesJournal of High Energy Physics, 2023
The Motzkin spin chain is a spin-1 frustration-free model introduced by Shor & Movassagh. The ground state is constructed by mapping random walks on the upper half of the square lattice to spin configurations. It has unusually large entanglement entropy [

T − W relation and free energy of the Heisenberg chain at a finite temperature

open access: yesJournal of High Energy Physics, 2021
A new nonlinear integral equation (NLIE) describing the thermodynamics of the Heisenberg spin chain is derived based on the t − W relation of the quantum transfer matrices. The free energy of the system in a magnetic field is thus obtained by solving the

Algebraic construction of quantum integrable models including inhomogeneous models [PDF]

open access: yes, 1999
Exploiting the quantum integrability condition we construct an ancestor model associated with a new underlying quadratic algebra. This ancestor model represents an exactly integrable quantum lattice inhomogeneous anisotropic model and at its various ...

Form-factors and complete basis of observables via separation of variables for higher rank spin chains

open access: yesJournal of High Energy Physics, 2022
Integrable sl $$ \mathfrak{sl} $$ (N) spin chains, which we consider in this paper, are not only the prototypical example of quantum integrable systems but also systems with a wide range of applications.

Scalar products of Bethe vectors in the 8-vertex model

open access: yesJournal of High Energy Physics, 2020
We obtain a determinant representation of normalized scalar products of on-shell and off-shell Bethe vectors in the inhomogeneous 8-vertex model. We consider the case of rational anisotropy parameter and use the generalized algebraic Bethe ansatz ...

Exact solution of the quantum integrable model associated with the twisted D 3 2 $$ {\mathrm{D}}_3^{(2)} $$ algebra

open access: yesJournal of High Energy Physics, 2022
We generalize the nested off-diagonal Bethe ansatz method to study the quantum chain associated with the twisted D 3 2 $$ {D}_3^{(2)} $$ algebra (or the D 3 2 $$ {D}_3^{(2)} $$ model) with either periodic or integrable open boundary conditions. We obtain

On the Bethe states of the one-dimensional supersymmetric t − J model with generic open boundaries

open access: yesJournal of High Energy Physics, 2017
By combining the algebraic Bethe ansatz and the off-diagonal Bethe ansatz, we investigate the supersymmetric t − J model with generic open boundaries. The eigenvalues of the transfer matrix are given in terms of an inhomogeneous T − Q relation, and the ...

Factorization identities and algebraic Bethe ansatz for D 2 2 $$ {D}_2^{(2)} $$ models

open access: yesJournal of High Energy Physics, 2021
We express D 2 2 $$ {D}_2^{(2)} $$ transfer matrices as products of A 1 1 $$ {A}_1^{(1)} $$ transfer matrices, for both closed and open spin chains. We use these relations, which we call factorization identities, to solve the models by algebraic Bethe ...

Universality of the one dimensional Bose gas with delta interaction

open access: yes, 2004
We consider several models of interacting bosons in a one dimensional lattice. Some of them are not integrable like the Bose-Hubbard others are integrable. At low density all of these models can be described by the Bose gas with delta interaction.
