Spontaneous polarization of spin 1 analogue of the eight-vertex model    [PDF]

Yas-Hiro Quano

The spin 1 analogue of the eight-vertex model is considered on the basis of free field representations of vertex operators in the $2\times 2$-fold fusion SOS model and vertex-face transformation. The spontaneous polarization of the model is obtained in terms of one-fold integral formula. Some limiting cases are discussed in order to examine the validity of the formula. Furthermore, we also present the integral formulae of the one-point function for the inhomogeneous twenty-one-vertex model.
