Quantum oscillations in graphene in the presence of disorder and interactions
Quantum oscillations in graphene are discussed. The effect of interactions are addressed by Kohn's theorem regarding de Haas--van Alphen oscillations, which states that electron-electron interactions cannot affect the oscillation frequencies as long as disorder is neglected and the system is sufficiently screened, which should be valid for chemical potentials not …
