Exact solution of the one-dimensional Hubbard model with arbitrary boundary magnetic fields
Yuan-Yuan Li, Junpeng Cao, Wen-Li Yang +2
The one-dimensional Hubbard model with arbitrary boundary magnetic fields is solved exactly via the Bethe ansatz methods. With the coordinate Bethe ansatz in the charge sector, the…
Nested off-diagonal Bethe ansatz and exact solutions of the su(n) spin chain with generic integrable boundaries
Junpeng Cao, Wen-Li Yang, Kangjie Shi +1
The nested off-diagonal Bethe ansatz method is proposed to diagonalize multi-component integrable models with generic integrable boundaries. As an example, the exact solutions of t…
Exact solution of the one-dimensional super-symmetric t-J model with unparallel boundary fields
Xin Zhang, Junpeng Cao, Wen-Li Yang +2
The exact solution of the one-dimensional super-symmetric t-J model under generic integrable boundary conditions is obtained via the Bethe ansatz methods. With the coordinate Bethe…
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 solution of the XXX spin-chain with arbitrary boundary conditions
Junpeng Cao, Wenli Yang, Kangjie Shi +1
With the off-diagonal Bethe ansatz method proposed recently by the present authors, we exactly diagonalize the spin chain with arbitrary boundary fields. By constructing a fu…
