Non-local features of the spin-orbit exciton in Kitaev materials
Blair W. Lebert, Subin Kim, Beom Hyun Kim +7
A comparative resonant inelastic x-ray scattering (RIXS) study of three well-known Kitaev materials is presented: -LiIrO, NaIrO, and -RuCl. Despite simila…
Intermediate Valence State in Revealed by Resonant X-ray Emission Spectroscopy
Felix Frontini, Blair W. Lebert, K. K. Cho +4
We report the temperature dependence of the Yb valence in the geometrically frustrated compound from 12 to 300 K using resonant X-ray emission spectroscopy at the…
Acoustic phonon dispersion of -RuCl
Blair W. Lebert, Subin Kim, Danil A. Prishchenko +4
Acoustic phonons have recently been posited as playing an integral role in explaining the half-quantized thermal Hall effect in -RuCl. Therefore, we present much needed inel…
Resonant inelastic x-ray scattering study of -RuCl: a progress report
Blair W Lebert, Subin Kim, Valentina Bisogni +3
Ru M-edge resonant inelastic x-ray scattering (RIXS) measurements of RuCl with 27 meV resolution reveals a spin-orbit exciton without noticeable splitting. We extract value…
Phonon anomalies with doping in superconducting oxychlorides Ca2-xCuO2Cl2
Blair W. Lebert, Hajime Yamamoto, Masaki Azuma +6
We measure the dispersion of the Cu-O bond-stretching phonon mode in the high-temperature superconducting parent compound CaCuOCl. Our density functional theory calcula…
Resonant inelastic X-ray scattering study of spin-wave excitations in the cuprate parent compound CaCuOCl
B. W. Lebert, M. P. M. Dean, A. Nicolaou +10
By means of resonant inelastic x-ray scattering at the Cu L edge, we measured the spin wave dispersion along 100 and 110 in the undoped cupr…
