Spectroscopic evidence for a molecular orbital Kondo insulator
Ke-Jun Xu, Kuan H. Hsu, Nathan Giles-Donovan +13
A Kondo insulator (KI) is a prototypical example of a highly entangled phase of matter, where many-body interactions between local moments and delocalized electrons engender the no…
Machine Learning to Predict Spectral Anisotropy in Valence-to-Core X-ray Emission Spectroscopy
Charles A. Cardot, John R. Tichenor, Seth M. Shjandemaar +3
Polarization analysis in x-ray spectroscopy provides an orientation dependent sensitivity to local bonding environments. For a cluster of atoms, polarization sensitivity is most of…
Negative Charge Transfer: Ground State Precursor towards High Energy Batteries
Eder G. Lomeli, Qinghao Li, Kuan H. Hsu +22
Modern energy applications, especially electric vehicles, demand high energy batteries. However, despite decades of intensive efforts, the highest energy density and commercially v…
X-ray Emission Spectropolarimetry of Strongly Anisotropic Single Crystal Systems using a Rowland Circle Geometry
Jared E. Abramson, Charles A. Cardot, Josh J. Kas +6
Polarization dependence has historically seen extensive use in x-ray spectroscopy to determine magnetic and local geometric properties, but more broadly as a way to gain extra sens…
