Operator content of the cyclic solid-on-solid models

Abstract

The operator content of the cyclic solid-on-solid models is derived under general boundary conditions by mapping the row-to-row transfer matrix onto the six-vertex model and XXZ Heisenberg chain. For the shift boundary conditions, the dimensions and spins of the primary operators are derived analytically from finite-size corrections to the scaling spectra. The full operator content agrees with results for a quantum chain model having the same local symmetry.
