Layer-dependent spin-resolved electronic structure of ferromagnetic triple-layered ruthenate SrRuO
Prosper Ngabonziza, Jonathan D. Denlinger, Alexei V. Fedorov +4
High-resolution angle- and spin-resolved photoemission spectroscopy (ARPES) of the triple-layered ruthenate SrRuO reveals features of the electronic structure that e…
Electronic Structure and Magnetism of the Triple-layered Ruthenate SrRuO
G. Gebreyesus, Prosper Ngabonziza, Jonah Nagura +3
We report electronic band structure calculations for SrRuO that displays both ferromagnetic and metamagnetic behavior. The density functional calculations find t…
Screening of a point charge: a fixed-node diffusion Monte Carlo study
Erik Koch, Olle Gunnarsson, Richard M. Martin
We study the static screening in a Hubbard-like model using fixed-node diffusion Monte Carlo. We find that the random phase approximation is surprisingly accurate even for metallic…
Fixed-node DMC for Fermions on a lattice: Application to the doped Fullerides
Erik Koch, Olle Gunnarsson, Richard M. Martin
Fullerides are crystals made from C60 molecules. When doped with alkali metals the valence electrons of the alkali atoms are transfered to the C60 molecules. We show how to set up…
Quantum Monte Carlo calculations for integer-doped Fullerides
Erik Koch, Olle Gunnarsson, Richard M. Martin
The doped Fullerides can be well described by a Hubbard model, which comprises the partly filled, threefold-degenerate t_1u orbital and the on-site Coulomb interaction U. The orbit…
