The two-impurity Anderson Hamiltonian is solved numerically by using the quantum Monte Carlo technique. We find that the inter-impurity spin susceptibility is strongly enhanced at low temperatures, significantly diverging from the well-known Ruderman-Kittel-Kasuya-Yoshida (RKKY) result which decays as $R^{-3}$.", "revisions": [ { "version": "v1", "updated": "2014-10-30T12:48:08.000Z" } ], "analyses": { "subjects": [ "75.75.-c", "73.22.Pr" ], "keywords": [ "magnetic impurities", "spin-spin correlations", "quantum monte carlo technique", "magnetic adatom impurities", "inter-impurity spin susceptibility" ], "tags": [ "journal article" ], "publication": { "doi": "10.1103/PhysRevB.91.125403", "journal": "Physical Review B", "year": 2015, "month": "Mar", "volume": 91, "number": 12, "pages": 125403 }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015PhRvB..91l5403G" } } }
