Phonon-induced linewidths of graphene electronic states
B. Hellsing, T. Frederiksen, F. Mazzola +2
The linewidths of the electronic bands originating from the electron-phonon coupling in graphene are analyzed based on model tight-binding calculations and experimental angle-resol…
Photoemission footprints of extrinsic plasmarons
Bo Hellsing, V. M. Silkin
A prediction how to experimentally distinguish excitations of extrinsic plasmarons from intrinsic plasmarons is presented. In surface systems where excitations of acoustic surface…
Plasmaron excitations in p(2x2)-K/Graphite
V. Chis, V. M. Silkin, B. Hellsing
A new type of plasmarons formed by the compound of photoelectrons and acoustic surface plasmon excitations is investigated in the system p(2x2)-K/Graphite. The physics behind these…
Orbital Selectivity in Hund's metals: The Iron Chalcogenides
N. Lanatà, H. U. R. Strand, G. Giovannetti +3
We show that electron correlations lead to a bad metallic state in chalcogenides FeSe and FeTe despite the intermediate value of the Hubbard repulsion and Hund's rule coupling…
