The inhomogeneous six-vertex model is a 2D multiparametric integrable statistical system. In the scaling limit it is expected to cover different classes of critical behaviour which, for the most part, have remained unexplored. For general values of the parameters and twisted boundary conditions the model possesses ${\rm U}(1)$ invariance. In this paper we discuss the restrictions imposed on the parameters for which additional global symmetries arise that are consistent with the integrable…

Scaling limit of the ${\cal Z}_2$ invariant inhomogeneous six-vertex model
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 numerical analysis of
Lattice regularisation of a non-compact boundary conformal field theory
Non-compact Conformal Field Theories (CFTs) are central to several aspects of string theory and condensed matter physics. They are characterised, in particular, by the appearance of a continuum of
Factorization identities and algebraic Bethe ansatz for $$ {D}_2^{(2)} $$ models
We express $D^{(2)}_{2}$ transfer matrices as products of $A^{(1)}_{1}$ transfer matrices, for both closed and open spin chains. We use these relations, which we call factorization identities, to
An Ising-type formulation of the six-vertex model
. We show that the celebrated six-vertex model of statistical mechanics (along with its multistate generalizations) can be reformulated as an Ising-type model with only a two-spin interaction. Such a
ODE/IQFT correspondence for the generalized affine sl(2) Gaudin model
An integrable system is introduced, which is a generalization of the sl(2) quantum affine Gaudin model. Among other things, the Hamiltonians are constructed and their spectrum is calculated within
ODE/IQFT correspondence for the generalized affine $$ \mathfrak{sl} $$(2) Gaudin model
Abstract An integrable system is introduced, which is a generalization of the $$ \mathfrak{sl} $$ sl (2) quantum affine Gaudin model. Among other things, the Hamiltonians are constructed and their
