An integrable Anderson-impurity problem embedded in the one-dimensional Hubbard model
Renjie Song, Mingchen Zheng, Junpeng Cao +1
An exactly solvable one-dimensional Hubbard model with a single Anderson impurity embedded at the boundary is constructed in the framework of the quantum inverse scattering method.…
Exact physical quantities of the spin chain model with generic open boundary conditions
Pengcheng Lu, Junpeng Cao, Wen-Li Yang +2
We study the quantum integrable spin chain model associated with the twisted algebra (or simply the model) under generic open boundary conditions. The Hamil…
Exact surface energies and boundary excitations of the Izergin-Korepin model with generic boundary fields
Pengcheng Lu, Junpeng Cao, Wen-Li Yang +2
The Izergin-Korepin model is an integrable model with the simplest twisted quantum affine algebra symmetry. Applying the method, we derive the homogeneous ze…
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…
Exact physical quantities of the XYZ spin chain in the thermodynamic limit
Zhirong Xin, Junpeng Cao, Wen-Li Yang +1
The thermodynamic limits of the XYZ spin chain with periodic or twisted boundary conditions are studied. By using the technique of characterizing the eigenvalue of the transfer mat…
Exact surface energy of the Hubbard model with nonparallel boundary magnetic fields
Pei Sun, Yi Qiao, Tao Yang +2
In this study, we explore the precise physical quantities in the thermodynamic limit of the one-dimensional Hubbard model with nonparallel boundary magnetic fields based on the off…
