Thermodynamic limit of the spin- XYZ spin chain with the antiperiodic boundary condition
Zhirong Xin, Yusong Cao, Xiaotian Xu +3
Based on its off-diagonal Bethe ansatz solution, we study the thermodynamic limit of the spin- XYZ spin chain with the antiperiodic boundary condition. The key point o…
Exact solution of an integrable anisotropic spin chain model
Yi Qiao, Pei Sun, Zhirong Xin +2
An integrable anisotropic Heisenberg spin chain with nearest-neighbour couplings, next-nearest-neighbour couplings and scalar chirality terms is constructed. After proving the inte…
Correlation functions of the XXZ spin chain with the twisted boundary condition
Yi Qiao, Zhirong Xin, Xiaotian Xu +4
The scalar products, form factors and correlation functions of the XXZ spin chain with twisted (or antiperiodic) boundary condition are obtained based on the inhomogeneous re…
Surface energy and elementary excitations of the XXZ spin chain with arbitrary boundary fields
Pei Sun, Zhi-Rong Xin, Yi Qiao +5
The thermodynamic properties of the XXZ spin chain with integrable open boundary conditions at the gaped region (i.e., the anisotropic parameter being a real number) are invest…
Exact solution of an integrable spin chain model
Yi Qiao, Zhirong Xin, Junpeng Cao +3
An integrable Heisenberg spin chain with nearest-neighbour couplings, next-nearest-neighbour couplings and Dzyaloshinski-Moriya interacton is constructed. The integrability of the…
Exact solution of the integrable spin chain with generic boundaries
Guang-Liang Li, Junpeng Cao, Panpan Xue +5
The off-diagonal Bethe ansatz method is generalized to the integrable model associated with the (or ) Lie algebra. By using the fusion technique, we obtain the complet…
