Experimental evidence of plasmarons and effective fine structure constant in electron-doped graphene/h-BN heterostructure

Abstract Electron-electron interaction is fundamental in condensed matter physics and can lead to composite quasiparticles called plasmarons, which strongly renormalize the dispersion and carry information of electron-electron coupling strength as defined by the effective fine structure constant $${...
