Effect of electron correlations on (001) Fe/MgO interfaces
Sergey V. Faleev, Oleg N. Mryasov, Mark van Schilfgaarde
We developed a parametrization of transmission probability that reliably captures essential elements of the tunneling process in magnetic tunnel junctions. The electronic structure…
First-principles Theory of Nonlocal Screening in Graphene
M. van Schilfgaarde, M. I. Katsnelson
Using the quasiparticle self-consistent GW (QSGW) and local-density (LD) approximations, we calculate the q-dependent static dielectric function, and derive an effective 2D dielect…
Low Energy, Coherent, Stoner-like Excitations in CaFeAs
L. Ke, M. van Schilfgaarde, J. J. Pulikkotil +2
Using linear-response density-functional theory, magnetic excitations in the striped phase of CaFeAs are studied as a function of local moment amplitude. We find a new…
