The ground state is proved to be unique; in addition, the total spin of the ground state is determined according to the lattice structure. To prove the assertions, an extension of the method of spin reflection positivity is given in terms of order preserving operator inequalities.", "revisions": [ { "version": "v1", "updated": "2020-07-28T15:25:55.000Z" } ], "analyses": { "keywords": [ "kondo lattice systems", "electron-phonon interaction", "study ground state properties", "order preserving operator inequalities", "spin reflection positivity" ], "note": { "typesetting": "TeX", "pages": 29, "language": "en", "license": "arXiv", "status": "editable" } } }
