The modulation of electron-electron interactions in graphene via temperature.

ORAL

Abstract

Near the charge neutral point, graphene exhibits interesting many-body interactions beyond what Fermi liquid theory can predict. We investigate such many-body effects in charge neutral graphene using angle-resolved photoemission spectroscopy. The electron band structure shows strong deviation from the characteristic linearity at low temperatures. Our findings suggest a possible realization of strong correlations between Dirac fermions in graphene via temperature.
