Concerning the latter we develop a multiple integral formula which applies for arbitrary states of the system with a smooth distribution of Bethe roots, including the ground state and finite temperature Gibbs-states. In the cases K<=4 we perform the explicit factorization of the multiple integral. In the case of K=3 we obtain the recent result of Kormos et.al., whereas our formula for K=4 is new. Numerical results are presented as well.", "revisions": [ { "version": "v3", "updated": "2011-09-27T14:26:05.000Z" } ], "analyses": { "keywords": [ "1d bose gas", "xxz chain", "scaling limit", "k-body local correlations", "multiple integral formula" ], "tags": [ "journal article" ], "publication": { "doi": "10.1088/1742-5468/2011/11/P11017", "journal": "Journal of Statistical Mechanics: Theory and Experiment", "year": 2011, "month": "Nov", "volume": 2011, "number": 11, "pages": 11017 }, "note": { "typesetting": "TeX", "pages": 23, "language": "en", "license": "arXiv", "status": "editable", "inspire": 925955, "adsabs": "2011JSMTE..11..017P" } } }
