Density matrix of a finite sub-chain of the Heisenberg anti-ferromagnet
H. Boos, M. Jimbo, T. Miwa +2
We consider a finite sub-chain on an interval of the infinite XXX model in the ground state. The density matrix for such a subsystem was described in our previous works for the mod…

Traces on the Sklyanin algebra and correlation functions of the eight-vertex model
H. Boos, M. Jimbo, T. Miwa +2
We propose a conjectural formula for correlation functions of the Z-invariant (inhomogeneous) eight-vertex model. We refer to this conjecture as Ansatz. It states that correlation…
