Damping of spinful excitons in LaCoO by thermal fluctuations: Theory and experiment
Atsushi Hariki, Ru-Pan Wang, Andrii Sotnikov +7
We present Co -edge resonant inelastic x-ray scattering (RIXS) of bulk LaCoO across the thermally-induced spin-state crossover around 100~K. Owing to a high energy resolut…
Unusual dynamic charge-density-wave correlations in HgBaCuO
B. Yu, W. Tabis, I. Bialo +6
The charge-density-wave (CDW) instability in the underdoped, pseudogap part of the cuprate phase diagram has been a major recent research focus, yet measurements of dynamic, energy…
Determining the Electron-Phonon Coupling in Superconducting Cuprates by Resonant Inelastic X-ray Scattering: Methods and Results on NdBaCuO
Lucio Braicovich, Matteo Rossi, Roberto Fumagalli +15
The coupling between lattice vibration quanta and valence electrons can induce charge density modulations and decisively influence the transport properties of materials, e.g. leadi…
Spin-orbit coupling and crystal-field distortions for a low-spin state in BaCoO
Y. Y. Chin, Z. Hu, H. -J. Lin +13
We have studied the electronic structure of BaCoO using soft x-ray absorption spectroscopy at the Co- and O- edges, magnetic circular dichroism at the Co-…
Experimental Determination of Momentum-Resolved Electron-Phonon Coupling
Matteo Rossi, Riccardo Arpaia, Roberto Fumagalli +9
We provide a novel experimental method to quantitatively estimate the electron-phonon coupling and its momentum dependence from resonant inelastic x-ray scattering (RIXS) spectra b…
Polarization resolved Cu -edge resonant inelastic x-ray scattering of orbital and spin excitations in NdBaCuO
R. Fumagalli, L. Braicovich, M. Minola +14
High resolution resonant inelastic x-ray scattering (RIXS) has proven particularly effective in the determination of crystal field and spin excitations in cuprates. Its strength li…
