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…
Exact solution of the quantum integrable model associated with the twisted algebra
Guang-Liang Li, Xiaotian Xu, Kun Hao +5
We generalize the nested off-diagonal Bethe ansatz method to study the quantum chain associated with the twisted algebra (or the model) with either periodic…
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…
Graded Off-diagonal Bethe ansatz solution of the spin chain model with generic integrable boundaries
Xiaotian Xu, Junpeng Cao, Yi Qiao +3
The graded off-diagonal Bethe ansatz method is proposed to study supersymmetric quantum integrable models (i.e., quantum integrable models associated with superalgebras). As an exa…
Exact ground state and elementary excitations of a topological spin chain
Yi Qiao, Pei Sun, Junpeng Cao +3
A novel Bethe Ansatz scheme is proposed to calculate physical properties of quantum integrable systems without symmetry. As an example, the anti-periodic XXZ spin chain, a t…
Off-diagonal Bethe Ansatz for the model
Guang-Liang Li, Junpeng Cao, Panpan Xue +5
The exact solutions of the model (or the quantum spin chain) with either periodic or general integrable open boundary conditions are obtained by using the off-d…
Off-diagonal Bethe Ansatz on the spin chain
Guang-Liang Li, Junpeng Cao, Panpan Xue +5
The (i.e., ) quantum integrable spin chains with both periodic and non-diagonal boundaries are studied via the off-diagonal Bethe Ansatz method. By using the fusion te…
