Scattering matrix of elementary excitations in the antiperiodic XXZ spin chain with η=iπ/3

Pei Sun, Jintao Yang, Yi Qiao +2

We study the thermodynamic limit of the antiperiodic XXZ spin chain with the anisotropic parameter $η = \frac{π i}{3}$ . We parameterize eigenvalues of the transfer matrix by their zer…

Surface energy of the one-dimensional supersymmetric $t - J$ model with general integrable boundary terms in the antiferromagnetic sector

Pei Sun, Yang-Yang Chen, Tao Yang +2

In this paper, we study the surface energy of the one-dimensional supersymmetric $t - J$ model with unparallel boundary magnetic fields, which is a typical $U (1)$ -symmetry broken qua…
