Quantum-group-invariant models: Bethe ansatz and finite-size spectrum
Holger Frahm, Sascha Gehrmann, Rafael I. Nepomechie +1
We consider the quantum integrable spin chain models associated with the Jimbo R-matrix based on the quantum affine algebra , subject to quantum-group-invariant boun…
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…
Scaling limit of the staggered six-vertex model with invariant boundary conditions
Holger Frahm, Sascha Gehrmann, Gleb A. Kotousov
We study the scaling limit of a statistical system, which is a special case of the integrable inhomogeneous six-vertex model. It possesses invarianc…
The spin chain and its finite-size spectrum
Holger Frahm, Sascha Gehrmann, Rafael I. Nepomechie +1
Using the analytic Bethe ansatz, we initiate a study of the scaling limit of the quasi-periodic spin chain. Supported by a detailed symmetry analysis, we determine the…
