Screening from $e_{g}$ states and antiferromagnetic correlations in $d^{(1, 2, 3)}$ perovskites: A $G W$ +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 $_{3}$ perovskites, using the parameter-free $G W$ +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 $U$ , which enters as matrix elements in some localized…
