Marginal-Fermi-liquid behavior from two-dimensional Coulomb interaction
Open accessAbstract
A full, nonperturbative renormalization group analysis of interacting electrons in a graphite layer is performed, in order to investigate the deviations from Fermi-liquid theory that have been observed in the experimental measures of a linear quasiparticle decay rate in graphite. The electrons are coupled through Coulomb interactions, which remain unscreened due to the semimetallic character of the layer. We show that the model flows towards the noninteracting fixed point for the whole range of couplings, with logarithmic corrections which signal the marginal character of the interaction separating Fermi-liquid and non-Fermi-liquid regimes.

“A strong coupling expansion is also possible, assuming that the number of electronic flavors justifies an RPA expansion, keeping only electron-hole bubble diagrams (González et al., 1999).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
