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…
Strong electron-phonon coupling in the sigma band of graphene
Federico Mazzola, Thomas Frederiksen, Thiagarajan Balasubramanian +3
First-principles studies of the electron-phonon coupling in graphene predict a high coupling strength for the band with values of up to 0.9. Near the top of the band, $…
Model study of the electron-phonon coupling in graphene; relative importance of intraband and interband scattering
H. Toren, L. Samuelsson, B. Hellsing
The aim of this model study of the electron-phonon coupling in graphene was to find out about the relative importance of the inter- and intraband scattering and which phonon modes…
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…
Efficient implementation of the Gutzwiller variational method
Nicola Lanatà, Hugo U. R. Strand, Xi Dai +1
We present a self-consistent numerical approach to solve the Gutzwiller variational problem for general multi-band models with arbitrary on-site interaction. The proposed method ge…
The Dynamical Mean Field Theory phase space extension and critical properties of the finite temperature Mott transition
Hugo U. R. Strand, Andro Sabashvili, Mats Granath +2
We consider the finite temperature metal-insulator transition in the half filled paramagnetic Hubbard model on the infinite dimensional Bethe lattice. A new method for calculating…
Model study of adsorbed metallic quantum dots: Na on Cu(111)
T. Torsti, V. Lindberg, M. J. Puska +1
We model electronic properties of the second monolayer Na adatom islands (quantum dots) on the Cu(111) surface covered homogeneously by the first Na monolayer. An axially-symmetric…
