Exact surface energy and helical spinons in the XXZ spin chain with arbitrary non-diagonal boundary fields
Yi Qiao, Junpeng Cao, Wen-Li Yang +2
An analytic method is proposed to compute the surface energy and elementary excitations of the XXZ spin chain with generic non-diagonal boundary fields. For the gapped case, in som…
On the complete-spectrum characterization of quantum integrable spin chains via the inhomogeneous T-Q relation
Junpeng Cao, Wen-Li Yang, Kangjie Shi +1
With the XXZ spin chains as examples, we prove two theorems: (1) the functional relations derived from the off-diagonal Bethe Ansatz scheme are the sufficient and necessary conditi…
Exact solution of the XXZ alternating spin chain with generic non-diagonal boundaries
Junpeng Cao, Wen-Li Yang, Kangjie Shi +1
The integrable XXZ alternating spin chain with generic non-diagonal boundary terms specified by the most general non-diagonal K-matrices is studied via the off-diagonal Bethe Ansat…
Exact solution of the spin-s Heisenberg chain with generic non-diagonal boundaries
Junpeng Cao, Shuai Cui, Wen-Li Yang +2
The off-diagonal Bethe ansatz method is generalized to the high spin integrable systems associated with the su(2) algebra by employing the spin-s isotropic Heisenberg chain model w…
Thermodynamic limit and surface energy of the XXZ spin chain with arbitrary boundary fields
Yuan-Yuan Li, Junpeng Cao, Wen-Li Yang +2
In two previous papers [26, 27], the exact solutions of the spin-1/2 chains with arbitrary boundary fields were constructed via the off-diagonal Bethe ansatz (ODBA). Here we introd…
Completeness and Bethe root distribution of the spin-1/2 Heisenberg chain with arbitrary boundary fields
Yuzhu Jiang, Shuai Cui, Junpeng Cao +2
Recently, the XXX spin chain with arbitrary boundary fields was successfully solved [1] via the off-diagonal Bethe ansatz method [2]. The correctness and the completeness of this s…
Off-diagonal Bethe ansatz solutions of the anisotropic spin-1/2 chains with arbitrary boundary fields
Junpeng Cao, Wen-Li Yang, Kangjie Shi +1
The anisotropic spin-1/2 chains with arbitrary boundary fields are diagonalized with the off-diagonal Bethe ansatz method. Based on the properties of the R-matrix and the K-matrice…
Spin-1/2 XYZ model revisit: general solutions via off-diagonal Bethe ansatz
Junpeng Cao, Shuai Cui, Wen-Li Yang +2
The spin-1/2 XYZ model with both periodic and anti-periodic boundary conditions is studied via the off-diagonal Bethe ansatz method. The exact spectra of the Hamiltonians and the B…
Off-diagonal Bethe ansatz and exact solution of a topological spin ring
Junpeng Cao, Wen-Li Yang, Kangjie Shi +1
A general method is proposed for constructing the Bethe ansatz equations of integrable models without U(1) symmetry. As an example, the exact spectrum of the XXZ spin ring with M{\…
Non-exclusion statistics: a generalization of Bose-Einstein's principle
Yupeng Wang
By constructing the super-particle representation of the free boson gas, we propose a new statistics in which the particles are non-exclusive. This statistics can be considered as…
