Large crystal local-field effects in the dynamical structure factor of rutile TiO2
I. G. Gurtubay, Wei Ku, J. M. Pitarke +4
We present ab initio time-dependent-density-functional calculations and non-resonant inelastic x-ray scattering measurements of the dynamical structure factor of rutile TiO2. Our c…

Temperature dependent d-d excitations in manganites probed by resonant inelastic x-ray scattering
S. Grenier, J. P. Hill, V. Kiryukhin +8
We report the observation of temperature dependent electronic excitations in various manganites utilizing resonant inelastic x-ray scattering (RIXS) at the Mn K-edge. Excitations w…

Exchange coupling in Eu monochalcogenides from first principles
J. Kunes, Wei Ku, W. E. Pickett
Using a density functional method with explicit account for strong Coulomb repulsion within the 4f shell, we calculate effective exchange parameters and the corresponding ordering…
