Since $\\cal T$ determines both the total and the elastic, spin-diagonal scattering cross sections, we are able to compute the full energy-, spin- and magnetic field dependence of the inelastic scattering cross section, $\\sigma_{\\rm inel}(\\omega)$. We find an almost linear frequency dependence of $\\sigma_{\\rm inel}(\\omega)$ below the Kondo temperature, $T_K$, which crosses over to a $\\sim \\omega^2$ behavior only at extremely low energies. Our method can be generalized to other quantum impurity models.", "revisions": [ { "version": "v2", "updated": "2004-03-31T15:00:52.000Z" } ], "analyses": { "keywords": [ "magnetic impurity", "numerical renormalization group method tocalculate", "single particle matrix elements", "magnetic field dependence", "spin-diagonal scattering cross sections" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
