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…
On the scaling behaviour of the alternating spin chain
Vladimir V. Bazhanov, Gleb A. Kotousov, Sergii M. Koval +1
In this note we report the results of our study of a 1D integrable spin chain whose critical behaviour is governed by a CFT possessing a continuous spectrum of scaling dimensions.…
