Exact physical quantities of a competing spin chain in the thermodynamic limit
Pengcheng Lu, Yi Qiao, Junpeng Cao +1
We study the exact physical quantities of a competing spin chain which contains many interesting and meaningful couplings including the nearest neighbor, next nearest neighbor, chi…
Exact surface energy of the spin chain with generic non-diagonal boundary reflections
Guang-Liang Li, Yi Qiao, Junpeng Cao +3
The exact solution of the quantum spin chain with generic non-diagonal boundary reflections is obtained. It is found that the generating functional of conserved quantit…
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…
Spectrum of the transfer matrices of the spin chains associated with the Lie algebra
Guang-Liang Li, Junpeng Cao, Xiao-Tian Xu +4
We study the exact solution of quantum integrable system associated with the twist Lie algebra, where the boundary reflection matrices have non-diagonal elements thus t…
