Jordan-Wigner fermionization for the one-dimensional Bariev model of three coupled XY chains
X. -W. Guan, A. Foerster, J. Links +1
The Jordan-Wigner fermionization for the one-dimensional Bariev model of three coupled XY chains is formulated. The Lax operator in terms of fermion operators and the quantum R-mat…
Integrable open boundary conditions for the Bariev model of three coupled XY spin chains
A. Foerster, M. D. Gould, X. -W. Guan +2
The integrable open-boundary conditions for the Bariev model of three coupled one-dimensional XY spin chains are studied in the framework of the boundary quantum inverse scattering…
Integrable variant of the one-dimensional Hubbard model
X. -W. Guan, A. Foerster, J. Links +3
A new integrable model which is a variant of the one-dimensional Hubbard model is proposed. The integrability of the model is verified by presenting the associated quantum R-matrix…
Exact solution for the Bariev model with boundary fields
A. Foerster, X. -W. Guan, J. Links +2
The Bariev model with open boundary conditions is introduced and analysed in detail in the framework of the Quantum Inverse Scattering Method. Two classes of independent boundary r…
Integrability of the vertex models with open boundary
M. J. Martins, X. W. Guan
We investigate various aspects of the integrability of the vertex models associated to the affine Lie algebra with open boundaries. We first study the solutions of the corr…
Algebraic Bethe ansatz for the one-dimensional Hubbard model with open boundaries
X. -W. Guan
The one-dimensional Hubbard model with open boundary conditions is exactly solved by means of algebraic Bethe ansatz. The eigenvalue of the transfer matrix, the energy spectrum as…
