The critical exponent associated to the divergence of the chiral correlation length is found to be equal to 1.7 already at very small values of disorder. Furthermore the helicity modulus jump is found larger than the universal value expected in the XY model.", "revisions": [ { "version": "v1", "updated": "1998-10-08T09:05:31.000Z" } ], "analyses": { "keywords": [ "fully frustrated xy model", "weak disorder", "monte carlo methods", "helicity modulus jump", "chiral correlation length" ], "tags": [ "journal article" ], "note": { "typesetting": "RevTeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable" } } }
