TLDR
Graphene's exchange and random-phase-approximation correlation energies are evaluated to show that the tendency of Coulomb interactions in lightly doped graphene to favor states with larger net chirality leads to suppressed spin and charge susceptibilities.Abstract:
Graphene is described at low energy by a massless Dirac equation whose eigenstates have definite chirality. We show that the tendency of Coulomb interactions in lightly doped graphene to favor states with larger net chirality leads to suppressed spin and charge susceptibilities. Our conclusions are based on an evaluation of graphene's exchange and random-phase-approximation correlation energies. The suppression is a consequence of the quasiparticle chirality switch which enhances quasiparticle velocities near the Dirac point.read more

Quantum theory of the electron liquid
TL;DR: In this paper, the Hartree-Fock approximation is used to approximate the linear response of an interacting electron liquid and the perturbative calculation of linear response functions is performed. But the results are limited to the one-dimensional electron gas at high magnetic field.
