Normal state of NdSrNiO from self-consistent +EDMFT
Francesco Petocchi, Viktor Christiansson, Fredrik Nilsson +2
The recent discovery of superconductivity in hole-doped NdNiO thin films has captivated the condensed matter physics community. Such compounds with a formal Ni valence have…
Screening from states and antiferromagnetic correlations in perovskites: A +EDMFT investigation
Francesco Petocchi, Fredrik Nilsson, Ferdi Aryasetiawan +1
We perform a systematic {\it ab initio} study of the electronic structure of Sr(V,Mo,Mn)O perovskites, using the parameter-free +EDMFT method. This approach self-consistent…
Position Representation of Effective Electron-Electron Interactions in Solids
Tor Jonas Sjöstrand, Fredrik Nilsson, Christoph Friedrich +1
An essential ingredient in many model Hamiltonians, such as the Hubbard model, is the effective electron-electron interaction , which enters as matrix elements in some localized…
Multitier self-consistent +EDMFT
Fredrik Nilsson, Lewin Boehnke, Philipp Werner +1
We discuss a parameter-free and computationally efficient ab initio simulation approach for moderately and strongly correlated materials, the multitier self-consistent +EDMFT m…
When strong correlations become weak: Consistent merging of and DMFT
Lewin Boehnke, Fredrik Nilsson, Ferdi Aryasetiawan +1
The cubic perovskite SrVO is generally considered to be a prototype strongly correlated metal with a characteristic three-peak structure of the -electron spectral function,…
Dynamical screening in La2CuO4
Philipp Werner, Rei Sakuma, Fredrik Nilsson +1
We show that the dynamical screening of the Coulomb interaction among Cu-d electrons in high-Tc cuprates is very strong and that a proper treatment of this effect is essential for…
