Energy-momentum dispersion relation of plasmarons in graphene
(Amer Physical Soc, College Pk, 2012)
The many-body correction to the band structure of a quasi-free-standing graphene layer is obtained within the Overhauser approach, where the electron-plasmon interaction is described as a field theoretical problem. We find ...
