Exact solution of a quantum integrable system associated with the exceptional Lie algebra
Guang-Liang Li, Junpeng Cao, Pei Sun +3
A quantum integrable spin chain model associated with the exceptional Lie algebra is studied. By using the fusion technique, the closed recursive relations among the fused tr…
Off-diagonal approach to the exact solution of quantum integrable systems
Yi Qiao, Junpeng Cao, Wen-Li Yang +2
We investigate the - scheme for the anti-ferromagnetic XXX spin chain under both periodic and open boundary conditions. We propose a new parametrization of the eigenvalues of…
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…
Root patterns and energy spectra of quantum integrable systems without symmetry: antiperiodic spin chain
Xiong Le, Yi Qiao, Junpeng Cao +3
Finding out root patterns of quantum integrable models is an important step to study their physical properties in the thermodynamic limit. Especially for models without symm…
T-W relation and free energy of the Heisenberg chain at a finite temperature
Pengcheng Lu, Yi Qiao, Junpeng Cao +3
A new nonlinear integral equation (NLIE) describing the thermodynamics of the Heisenberg spin chain is derived based on the t-W relation of the quantum transfer matrices. The free…
