Singularity Cancellation in Fermion Loops through Ward Identities | C.Kopper
; J. Magnen
; | Date: |
28 Jul 2000 | Subject: | Strongly Correlated Electrons | cond-mat.str-el | Affiliation: | Centre de Physique Theorique, Ecole Polytechnique | Abstract: | Recently Neumayr and Metzner have shown that the connected N-point density- correlation functions of the two-dimensional and the one-dimensional Fermi gas at one-loop order generically vanish/are regular in the small momentum/small energy-momentum limits. Their result is based on an explicit analysis in the sequel of results of Feldman et al.[2]. In this note we use Ward identities to give a proof of the same fact - in a considerably shortened and simplified way - for any dimension of space. | Source: | arXiv, cond-mat/0007478 | Services: | Forum | Review | PDF | Favorites |
