Screened exchange dynamical mean field theory and its relation to density functional theory: SrVO3 and SrTiO3
Ambroise van Roekeghem, Silke Biermann
We present the first application of a recently proposed electronic-structure scheme to transition metal oxides: screened exchange dynamical mean-field theory includes non-local exc…
Camelback-shaped band reconciles heavy electron behavior with weak electronic Coulomb correlations in superconducting TlNi2Se2
N. Xu, C. E. Matt, P. Richard +16
Using high-resolution photoemission spectroscopy and first-principles calculations, we characterize superconducting TlNiSe as a material with weak electronic Coulomb correl…
Correlation-induced self-doping in intercalated iron-pnictide superconductor Ba2Ti2Fe2As4O
Junzhang Ma, Ambroise van Roekeghem, Pierre Richard +14
The electronic structure of the intercalated iron-based superconductor Ba2Ti2Fe2As4O (Tc - 21.5 K) has been investigated by using angle-resolved photoemission spectroscopy and comb…
Dynamical correlations and screened exchange on the experimental bench: spectral properties of the cobalt pnictide BaCo2As2
Ambroise van Roekeghem, Thomas Ayral, Jan M. Tomczak +7
Understanding the Fermi surface and low-energy excitations of iron or cobalt pnictides is crucial for assessing electronic instabilities such as magnetic or superconducting states.…
