Renormalization group for the \(XYZ\) model. (English) Zbl 0966.82007
Summary: A renormalization group analysis of the critical properties of the \(XYZ\) chain in the case of small anisotropy and \(J_3\) is performed. Some critical indices are computed and rigorous bounds on the large distance decay of the two point correlation function are found.
