Efficient GW calculations via the interpolation of the screened interaction in momentum and frequency space: The case of graphene
Alberto Guandalini, Dario A. Leon, Pino D'Amico +4
The GW self-energy may become computationally challenging to evaluate because of frequency and momentum convolutions. These difficulties were recently addressed by the development…
Frequency dependence in GW made simple using a multi-pole approximation
Dario A. Leon, Claudia Cardoso, Tommaso Chiarotti +3
In the approximation, the screened interaction is a non-local and dynamical potential that usually has a complex frequency dependence. A full description of such dependenc…
Narrowing of d bands of FeCo layers intercalated under graphene
Daniela Pacilè, Claudia Cardoso, Giulia Avvisati +7
We report on the electronic properties of an artificial system obtained by the intercalation of equiatomic FeCo layers under graphene grown on Ir(111). Upon intercalation, the FeCo…
Magnetic response and electronic states of well defined Graphene/Fe/Ir(111) heterostructure
Claudia Cardoso, Giulia Avvisati, Pierluigi Gargiani +7
We investigate a well defined heterostructure constituted by magnetic Fe layers sandwiched between graphene (Gr) and Ir(111). The challenging task to avoid Fe-C solubility and Fe-I…
