Marginal-Fermi-liquid behavior from two-dimensional Coulomb interaction
Marginal-Fermi-liquid behavior from two-dimensional Coulomb interaction
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 …
