Toward Functionalized Ultrathin Oxide Films: the Impact of Surface Apical Oxygen
Judith Gabel, Matthias Pickem, Philipp Scheiderer +12
Thin films of transition metal oxides open up a gateway to nanoscale electronic devices beyond silicon characterized by novel electronic functionalities. While such films are commo…
Zoology of spin and orbital fluctuations in ultrathin oxide films
Matthias Pickem, Josef Kaufmann, Karsten Held +1
Many metallic transition-metal oxides turn insulating when grown as films that are only a few unit-cells thick. The microscopic origins of these thickness induced metal-to-insulato…
Broadening and sharpening of the Drude peak through antiferromagnetic fluctuations
Paul Worm, Clemens Watzenböck, Matthias Pickem +2
Antiferromagnetic or charge density wave fluctuations couple with light through the recently discovered π-ton contribution to the optical conductivity, and quite generically consti…
Self-consistent ladder DA approach
Josef Kaufmann, Christian Eckhardt, Matthias Pickem +3
We present and implement a self-consistent DA approach for multi-orbital models and ab initio materials calculations. It is applied to the one-band Hubbard model at various inte…
Statistical error estimates in dynamical mean-field theory and extensions thereof
Patrick Kappl, Markus Wallerberger, Josef Kaufmann +2
We employ the jackknife algorithm to analyze the propagation of the statistical quantum Monte Carlo error through the Bethe--Salpeter equation. This allows us to estimate the error…
