Exact solution of the XXZ alternating spin chain with generic non-diagonal boundaries

Cao, Junpeng, Wen‐Li Yang, Kangjie Shi +1 more

The integrable XXZ alternating spin chain with generic non-diagonal boundary terms specified by the most general non-diagonal K-matrices is studied via the off-diagonal Bethe Ansatz method. Based on the intrinsic properties of the fused R-matrices and K-matrices, we obtain certain closed operator identities and conditions, which allow us to construct an inhomogeneous T-Q relation and the associated Bethe Ansatz equations accounting for the eigenvalues of the transfer matrix.

Exact surface energy of the D2(1) spin chain with generic non-diagonal boundary reflections

Guang-Liang Li, Yi Qiao, Junpeng Cao +3 more

The exact solution of the D2(1) quantum spin chain with generic non-diagonal boundary reflections is obtained. It is found that the generating functional of conserved quantities of the system can be factorized as the product of transfer matrices of two anisotropic XXZ spin chains with open boundary conditions. By using the factorization identities and the fusion technique, the eigenvalues and the Bethe ansatz equations of the model are obtained. The eigenvalues are also parameterized by the zero roots of the transfer matrix, and the patterns of root distributions are obtained. Based on them, ground states energy and the surface energies induced by the twisted boundary magnetic fields in the thermodynamic limit are obtained. These results are checked by the numerical calculations. The corresponding isotropic limit is also discussed. The results given in this paper are the foundation to study the exact physical properties of high rank Dn(1) model by using the nested processes.

Spectrum of the quantum integrable $$ {D}_2^{(2)} $$ spin chain with generic boundary fields

Guang-Liang Li, Junpeng Cao, Wen‐Li Yang +2 more

Abstract Exact solution of the quantum integrable $$ {D}_2^{(2)} $$ D 2 2 spin chain with generic integrable boundary fields is constructed. It is found that the transfer matrix of this model can be factorized as the product of those of two open staggered anisotropic XXZ spin chains. Based on this identity, the eigenvalues and Bethe ansatz equations of the $$ {D}_2^{(2)} $$ D 2 2 model are derived via off-diagonal Bethe ansatz.
