The thermal conductivity $\\kappa(\\omega)$ of this model has $\\Re\\kappa(\\omega)=\\tilde\\kappa \\delta(\\omega)$, i.e. it is infinite for zero frequency $\\omega$. The weight $\\tilde\\kappa$ of the delta peak is calculated exactly by a lattice path integral formulation. Numerical results for wide ranges of temperature and anisotropy are presented. The low and high temperature limits are studied analytically.", "revisions": [ { "version": "v1", "updated": "2001-12-24T18:34:55.000Z" } ], "analyses": { "keywords": [ "xxz chain", "arbitrary temperature", "quasi 1d magnetic systems", "lattice path integral formulation", "high temperature limits" ], "tags": [ "journal article" ], "publication": { "journal": "Journal of Physics A Mathematical General", "year": 2002, "month": "Mar", "volume": 35, "number": 9, "pages": 2173 }, "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable", "inspire": 581339, "adsabs": "2002JPhA...35.2173K" } } }
