Ab initio dynamical vertex approximation
Anna Galler, Patrik Thunström, Patrik Gunacker +2
Diagrammatic extensions of dynamical mean field theory (DMFT) such as the dynamical vertex approximation (DA) allow us to include non-local correlations beyond DMFT on all lengt…
Non-perturbative landscape of the Mott-Hubbard transition: Multiple divergence lines around the critical endpoint
T. Schäfer, S. Ciuchi, M. Wallerberger +5
We analyze the highly non-perturbative regime surrounding the Mott-Hubbard metal-to-insulator transition (MIT) by means of dynamical mean field theory calculations at the two-parti…
High photon energy spectroscopy of NiO: experiment and theory
S. K. Panda, Banabir Pal, Suman Mandal +12
We have revisited the valence band electronic structure of NiO by means of hard x-ray photoemission spectroscopy (HAXPES) together with theoretical calculations using both the GW m…
