- Abstract
The subject matter of this work is a 1D quantum spin - [Formula presented] chain associated with the inhomogeneous six-vertex model possessing an additional Z
r symmetry. The model is studied in a certain parametric domain, where it is critical. Within the ODE/IQFT approach, a class of ordinary differential equations and a quantization condition are proposed which describe the scaling limit of the system. Some remarkable features of the CFT underlying the critical behaviour are observed. Among them is an infinite degeneracy of the conformal primary states and the presence of a continuous component in the spectrum in the case of even r.
