Thermodynamic limit and boundary energy of the spin-1 Heisenberg chain with non-diagonal boundary fields

Zhihan Zheng, Pei Sun, Xiaotian Xu +3

The thermodynamic limit and boundary energy of the isotropic spin-1 Heisenberg chain with non-diagonal boundary fields are studied. The finite size scaling properties of the inhomo…

Exact solutions of the quantum spin chain

Guang-Liang Li, Panpan Xue, Pei Sun +5

We study the exact solutions of quantum integrable model associated with the Lie algebra, with either a periodic or an open one with off-diagonal boundary reflections, by gen…

Exact ground state and elementary excitations of a topological spin chain

Yi Qiao, Pei Sun, Junpeng Cao +3

A novel Bethe Ansatz scheme is proposed to calculate physical properties of quantum integrable systems without symmetry. As an example, the anti-periodic XXZ spin chain, a t…

Exact solution of an integrable anisotropic spin chain model

Yi Qiao, Pei Sun, Zhirong Xin +2

An integrable anisotropic Heisenberg spin chain with nearest-neighbour couplings, next-nearest-neighbour couplings and scalar chirality terms is constructed. After proving the inte…

Off-diagonal Bethe Ansatz on the spin chain

Guang-Liang Li, Junpeng Cao, Panpan Xue +5

The (i.e., ) quantum integrable spin chains with both periodic and non-diagonal boundaries are studied via the off-diagonal Bethe Ansatz method. By using the fusion te…

Surface energy and elementary excitations of the XXZ spin chain with arbitrary boundary fields

Pei Sun, Zhi-Rong Xin, Yi Qiao +5

The thermodynamic properties of the XXZ spin chain with integrable open boundary conditions at the gaped region (i.e., the anisotropic parameter being a real number) are invest…
