Experimental evidence for the importance of Hund's exchange interaction for the incoherence of the charge carriers in iron-based superconductors
J. Fink, E. D. L. Rienks, S. Thirupathaiah +10
Angle-resolved photoemission spectroscopy (ARPES) is used to study the scattering rates of charge carriers from the hole pockets near Gamma in the iron-based high-Tc hole doped sup…
ARPES observation of Mn-pnictide hybridization and negligible band structure renormalization in BaMnAs and BaMnSb
W. -L. Zhang, P. Richard, A. van Roekeghem +14
We performed an angle-resolved photoemission spectroscopy study of BaMnAs and BaMnSb, which are isostructural to the parent compound BaFeAs of the 122 famil…
High throughput thermal conductivity of high temperature solid phases: The case of oxide and fluoride perovskites
Ambroise van Roekeghem, Jesús Carrete, Corey Oses +2
Using finite-temperature phonon calculations and machine-learning methods, we calculate the mechanical stability of about 400 semiconducting oxides and fluorides with cubic perovsk…
Hubbard interactions in iron-based pnictides and chalcogenides: Slater parametrization, screening channels and frequency dependence
Ambroise van Roekeghem, Loïg Vaugier, Hong Jiang +1
We calculate the strength of the frequency-dependent on-site electronic interactions in the iron pnictides LaFeAsO, BaFe2As2, BaRu2As2, and LiFeAs and the chalcogenide FeSe from fi…
Angle-resolved spectroscopy study of Ni-based superconductor SrNiAs
L. -K. Zeng, P. Richard, A. van Roekeghem +7
We performed an angle-resolved photoemission spectroscopy study of the Ni-based superconductor SrNiAs. Electron and hole Fermi surface pockets are observed, but their diffe…
Anomalous thermal conductivity and suppression of negative thermal expansion in ScF3
Ambroise van Roekeghem, Jesús Carrete, Natalio Mingo
The empty perovskite ScF3 exhibits negative thermal expansion up to 1100 K. We demonstrate that ab-initio calculations of temperature-dependent effective phonon spectra allow to qu…
