We are paricularly interested in the possible gapless and gapped chiral phases, in which the chirality \\kappa_l = S_l^x S_{l+1}^y - S_l^y S_{l+1}^x exhibits a finite long-range order whereas the spin correlation decays either algebraically or exponentially. We show that the gapless chiral phase appears in a broad region of the phase diagram for general S. By contrast, the gapped chiral phase is found for integer S in a narrow region of the phase diagram, while it has not been identified for half-odd integer S within our numerical accuracy. By combining the results with our previous result for S = 1, we discuss the S-dependence of the phase diagram. The prediction from a bosonization analysis on the decay exponent of the spin correlation is verified.", "revisions": [ { "version": "v1", "updated": "2000-10-19T10:21:09.000Z" } ], "analyses": { "keywords": [ "frustrated spin-s xxz chain", "ground state phase diagrams", "chiral ordered phases", "gapped chiral phase", "spin correlation" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
