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…
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.…
Gravitational lens equation. Critical solutions and magnification near folds and cusps
A. N. Alexandrov, S. M. Koval, V. I. Zhdanov
We study approximate solutions of the gravitational lens equation and corresponding lens magnification factor near the critical point. This consideration is based on the Taylor exp…
