| dc.description | A general spin model on the Cayley tree lattice, which includes both the q component Potts (1952) and the Ashkin-Teller (1943) models, is considered. The free energy in zero field is evaluated in a closed form and found to be analytic in temperature. The model exhibits no long-range order in the sense that the probability of finding two sites far away to be in spin states alpha and beta is constant, independent of alpha and beta . The susceptibility per site, chi <sub>R</sub>, for a region R in the centre of the lattice, defined to be the summation of the site-site correlations between R and the whole lattice L. For the linear size of R to be any finite fraction of that of L, chi <sub>R</sub> diverges at the Bethe-Peierls temperature(s) T<sub>BP</sub>, while for R identical to L, chi <sub>R</sub> diverges at temperature(s) different from T<sub>BP</sub>. |
