RSOS models

introduction

• restricted solid-on-solid (RSOS) models
• also called as ABF(Andrews-Baxter-Forrester models)
• class of a spin system
• IBF(interaction round a face) model
• vertex counterpart is Belavin's generalization of the 8-vertex model

physical description

• a rough, discrete analogon of a gently fluctutationg surface of a liquid
• neighboring points cannot have heights which differ much from each other
• local energy density is given by the surface energy

height variable

• to each site i, we assign a height variable

critical RSOS model

• A_3 RSOS model = Ising models
• D_4 RSOS model = 3-states Potts model

Pierre Mathieu, Combinatorics of RSOS paths

Every minimal model in conformal field theory can be viewed as the scaling limit of a restricted-solid-on-solid (RSOS) model at criticality. States in irreducible modules of the minimal model M(p',p) can be described combinatorially by paths that represent configurations in the corresponding RSOS model, dubbed RSOS(p',p). These paths are in one-to-one correspondence with tableaux with prescribed hook differences. For p'=2, these are tableaux with successive ranks in a prescribed interval, which are known to be related to the Bressoud paths (whose generating function is the sum side of the Andrews-Gordon identity). We show how the RSOS(2,p) paths can be directly related to these paths. Generalizing this construction, we arrive at a representation of RSOS paths in terms of generalized Bressoud paths (for p>2p'). These new paths have a simple weighting and a natural particle interpretation. This then entails a natural particle spectrum for RSOS paths, which can be interpreted in terms of the kinks and breathers of the restricted sine-Gordon model.
