Here they are given by the operator-valued matrix elements of the monodromy matrix of the spin-1/2 XXZ spin chain. In the paper we call an arbitrary matrix element of a local operator between two Bethe eigenstates a form factor of the operator. We derive all important formulas of the fusion method in detail. We thus revise the derivation of the higher-spin XXZ form factors given in a previous paper. The revised method has several interesting applications in mathematical physics. For instance, we express the spin-$s$ XXZ correlation function of an arbitrary entry at zero temperature in terms of a sum of multiple integrals.", "revisions": [ { "version": "v2", "updated": "2011-08-30T11:20:43.000Z" } ], "analyses": { "keywords": [ "integrable spin-s xxz chain", "correlation function", "reduction formula", "application", "higher-spin xxz form factors" ], "tags": [ "journal article" ], "publication": { "doi": "10.1088/1742-5468/2012/04/P04001", "journal": "Journal of Statistical Mechanics: Theory and Experiment", "year": 2012, "month": "Apr", "volume": 2012, "number": 4, "pages": 4001 }, "note": { "typesetting": "TeX", "pages": 41, "language": "en", "license": "arXiv", "status": "editable", "inspire": 901093, "adsabs": "2012JSMTE..04..001D" } } }
