The open XXZ chain at and the boundary quantum Knizhnik-Zamolodchikov equations
Christian Hagendorf, Jean Liénardy
The open XXZ spin chain with the anisotropy parameter and diagonal boundary magnetic fields that depend on a parameter is studied. For real , the exact finite…
On the transfer matrix of the supersymmetric eight-vertex model. II. Open boundary conditions
Christian Hagendorf, Jean Liénardy
The transfer matrix of the square-lattice eight-vertex model on a strip with vertical lines and open boundary conditions is investigated. It is shown that for vertex…
On the transfer matrix of the supersymmetric eight-vertex model. I. Periodic boundary conditions
Christian Hagendorf, Jean Liénardy
The square-lattice eight-vertex model with vertex weights obeying the relation and periodic boundary conditions is considered. It is…
Open spin chains with dynamic lattice supersymmetry
Christian Hagendorf, Jean Liénardy
The quantum spin XXZ chain with anisotropy parameter possesses a dynamic supersymmetry on the lattice. This supersymmetry and a generalisation to higher spin are inv…
