Large Kohn anomaly and phonon collapse induced by charge density wave in UPt $_{2}$ Si $_{2}$

Jooseop Lee, Greta L. Chappell, Ryan E. Baumbach +2

Using high-energy-resolution inelastic x-ray scattering, we observe anomalous softening and damping of the transverse acoustic phonon in UPt $_{2}$ Si $_{2}$ as the system is cooled towar…

Structural transition and uranium valence change in UTe $_{2}$ at high pressure revealed by x-ray diffraction and spectroscopy

Yuhang Deng, Eric Lee-Wong, Camilla M. Moir +9

High pressure x-ray diffraction up to 30 GPa and resonant emission x-ray spectroscopy and partial fluorescence yield x-ray absorption spectroscopy up to 52 GPa were used to study h…
