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=iπ/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=iπ/3 by means of the t-W method. We parameterize the eigenvalues of both the transfer matrix a…
Root patterns and exact surface energy of the spin-1 Heisenberg model with generic open boundaries
Jiasheng Dong, Pengcheng Lu, Junpeng Cao +3
We investigate the thermodynamic limit and exact surface energy of the isotropic spin-1 Heisenberg chain with integrable generic open boundary conditions by a novel Bethe ansatz me…
Exact physical quantities of a competing spin chain in the thermodynamic limit
Pengcheng Lu, Yi Qiao, Junpeng Cao +1
We study the exact physical quantities of a competing spin chain which contains many interesting and meaningful couplings including the nearest neighbor, next nearest neighbor, chi…
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…
Coherence of an extended central spin model with a coupled spin bath
Pengcheng Lu, Hai-Long Shi, Like Cao +4
We study an extended central spin model with an isotropic nearest-neighbour spin-exchange interaction among the bath spins. The system is controllable by external magnetic fields a…
