We argue that the low-energy spectrum of the system consists of acoustic density waves and the spin excitations described by an effective ferromagnetic spin chain with a small exchange constant J. We use this description to compute the dynamic spin structure factor and the spectral functions of the system.", "revisions": [ { "version": "v2", "updated": "2008-08-12T16:43:20.000Z" } ], "analyses": { "subjects": [ "05.30.Jp", "75.10.Pq" ], "keywords": [ "spectral functions", "strongly interacting", "dynamic spin structure factor", "small exchange constant", "effective ferromagnetic spin chain" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "year": 2008, "month": "Oct", "volume": 101, "number": 17, "pages": 170403 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008PhRvL.101q0403M" } } }
