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…
T-W relation and free energy of the antiperiodic XXZ chain with η=iÏ/3 at a finite temperature
Pengcheng Lu, Junpeng Cao, Wen-Li Yang +2
We study the thermodynamics of the antiperiodic XXZ chain with anisotropy parameter η=iÏ/3 by means of the t-W method. We parameterize the eigenvalues of both the transfer matrix…
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…
