X-ray Absorption and Resonant X-ray Emission at the Carbon Edge of LiCO
John Vinson, Terrence Jach, Rainer Unterumsberger +2
While highly successful, density functional theory is known to have limitations owing to its neglect of many-body electron-electron interactions. This neglect leads to errors in th…
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…
Direct Observation of the Lindhard Continuum using Resonant Inelastic X-ray Scattering
Eder G. Lomeli, Sarbajaya Kundu, Yi-De Chuang +12
Understanding the excitations of quantum materials is essential for unraveling how their microscopic constituents interact. Among these, particle-hole excitations form a particular…
Non-resonant two-photon x-ray absorption in Cu
J. J. Kas, J. J. Rehr, J. Stohr +1
We present a real-space Green's function theory and calculations of two-photon x-ray absorption (TPA). Our focus is on non-resonant K-shell TPA in metallic Cu, which has been obser…
