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…

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…

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…
