This monograph introduces an exact model for a critical spin chain with arbitrary spin S, which includes the Haldane--Shastry model as the special case S=1/2.
Synopsis
Unlike the spinons in the Haldane-Shastry model, those proposed here obey non-abelian statistics and integrate classical and fresh concepts. The new model this volume introduces is derived by mapping exact models of quantized Hall states into spin chains.
