Scaling limit of the ground state Bethe roots for the inhomogeneous XXZ spin- $\frac{1}{2}$ chain

Sascha Gehrmann, Gleb A. Kotousov, Sergei L. Lukyanov

It is known that for the Heisenberg XXZ spin- $\frac{1}{2}$ chain in the critical regime, the scaling limit of the vacuum Bethe roots yields an infinite set of numbers that coincide…

Finite-size spectrum of the staggered six-vertex model with antidiagonal boundary conditions

Holger Frahm, Sascha Gehrmann

The finite-size spectrum of the critical staggered six-vertex model with antidiagonal boundary conditions is studied. Similar to the case of periodic boundary conditions, we identi…
