Abstract:
We compute exact vacuum expectation values of physically relevant scaling
fields in the perturbed ZN parafermionic models. Our algebraic method is
based on analyzing vertex operators in the corresponding off-critical lattice
model. The results coincide with the expressions derived by perturbed
conformal field theory methods.
