Exact physical quantities of the XYZ spin chain in the thermodynamic limit
Zhirong Xin, Junpeng Cao, Wen-Li Yang +1
The thermodynamic limits of the XYZ spin chain with periodic or twisted boundary conditions are studied. By using the technique of characterizing the eigenvalue of the transfer mat…
Surface energy and elementary excitations of the XYZ spin chain with integrable open boundary fields
Zhirong Xin, Junpeng Cao, Wen-Li Yang +1
We study the thermodynamic limit of the anisotropic XYZ spin chain with non-diagonal integrable open boundary conditions. Although the -symmetry is broken, by using the new p…
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…
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…
