Critical properties of the Izergin-Korepin and solvable O(n) models and their related quantum spin chains
The central charge of the Izergin-Korepin model the corresponding quantum spin chain, and the O(n) model is calculated analytically via the Bethe ansatz. The calculation extends a technique recently developed for the Zamolodchikov-Fateev model. In addition critical exponents and the central charge for these models are obtained from numerical solutions …
