ODE/IQFT correspondence for the generalized affine Gaudin model
Gleb A. Kotousov, Sergei L. Lukyanov
An integrable system is introduced, which is a generalization of the quantum affine Gaudin model. Among other things, the Hamiltonians are constructed and their…
Some Algebraic Aspects of the Inhomogeneous Six-Vertex Model
Vladimir V. Bazhanov, Gleb A. Kotousov, Sergii M. Koval +1
The inhomogeneous six-vertex model is a 2 multiparametric integrable statistical system. In the scaling limit it is expected to cover different classes of critical behaviour whi…
Scaling limit of the invariant inhomogeneous six-vertex model
Vladimir V. Bazhanov, Gleb A. Kotousov, Sergii M. Koval +1
The work contains a detailed study of the scaling limit of a certain critical, integrable inhomogeneous six-vertex model subject to twisted boundary conditions. It is based on a nu…
Equilibrium density matrices for the 2D black hole sigma models from an integrable spin chain
Vladimir V. Bazhanov, Gleb A. Kotousov, Sergei L. Lukyanov
This work concerns the quantum Lorentzian and Euclidean black hole non-linear sigma models. For the Euclidean black hole sigma model an equilibrium density matrix is proposed, whic…
Spectrum of the reflection operators in different integrable structures
Gleb A. Kotousov, Sergei L. Lukyanov
The reflection operators are the simplest examples of the non-local integrals of motion, which appear in many interesting problems in integrable CFT. For the so-called Fateev, quan…
Bethe state norms for the Heisenberg spin chain in the scaling limit
Gleb A. Kotousov, Sergei L. Lukyanov
In this paper we discuss the norms of the Bethe states for the spin one-half Heisenberg chain in the critical regime. Our analysis is based on the ODE/IQFT correspondence. Together…
