Exact physical quantities of the spin chain model with generic open boundary conditions
Pengcheng Lu, Junpeng Cao, Wen-Li Yang +2
We study the quantum integrable spin chain model associated with the twisted algebra (or simply the model) under generic open boundary conditions. The Hamil…
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…
Exact surface energies and boundary excitations of the Izergin-Korepin model with generic boundary fields
Pengcheng Lu, Junpeng Cao, Wen-Li Yang +2
The Izergin-Korepin model is an integrable model with the simplest twisted quantum affine algebra symmetry. Applying the method, we derive the homogeneous ze…
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…
Exact solution of the -deformed vertex model with open boundaries
Guang-Liang Li, Junpeng Cao, Yi Qiao +1
In this paper, we study the exact solution of the -deformed quantum lattice model with non-diagonal open boundary condition. We demonstrate the crossing symmetry of…
Spectrum of the quantum integrable spin chain with generic boundary fields
Guang-Liang Li, Junpeng Cao, Wen-Li Yang +2
Exact solution of the quantum integrable spin chain with generic integrable boundary fields is constructed. It is found that the transfer matrix of this model can be fa…
