Exact solution of an integrable spin chain model
Yi Qiao, Zhirong Xin, Junpeng Cao +3
An integrable Heisenberg spin chain with nearest-neighbour couplings, next-nearest-neighbour couplings and Dzyaloshinski-Moriya interacton is constructed. The integrability of the…

Thermodynamic limit and twisted boundary energy of the XXZ spin chain with antiperiodic boundary condition
Zhirong Xin, Yi Qiao, Kun Hao +4
We investigate the thermodynamic limit of the inhomogeneous T-Q relation of the antiferromagnetic XXZ spin chain with antiperiodic boundary condition. It is shown that the contribu…

Twisted boundary energy and low energy excitation of the XXZ spin torus at the ferromagnetic region
Yi Qiao, Zhirong Xin, Kun Hao +4
We investigate the thermodynamic limit of the one-dimensional ferromagnetic XXZ model with twisted (or antiperiodic ) boundary condition. It is shown that the distribution of the B…
