A vertex operator approach for correlation functions of Belavin's (ZZ)-symmetric model

摘要

Belavin's (ZZ)-symmetric model is considered on the basis of bosonization of vertex operators in the A_(n-1)~(1) model and vertex—face transformation. The corner transfer matrix (CTM) Hamiltonian of the (ZZ)-symmetric model and tail operators are expressed in terms of bosonized vertex operators in the A_(n-1)~(1)model. Correlation functions of the (ZZ)-symmetric model can be obtained by using these objects, in principle. In particular, we calculate spontaneous polarization, which reproduces the result we obtained in 1993.
