Spinon statistics in integrable spin- S Heisenberg chains
Abstract
The spectrum of the integrable spin- S Heisenberg chains is completely characterized in terms of spin- {1}/{2} spinons. In the continuum limit they form a quasi-particle basis to the higher level SU(2) Wess-Zumino-Witten (WZW) models. Enumerating the spinon states in finite systems we obtain effective single particle distribution functions for these objects which generalize Haldane's generalized exclusion principle to quasi-particles with non-Abelian exchange statistics.
