Transition-Metal-Oxygen Covalency Controls Ligand-Hole Stability in Li-Rich Cathode
Kuan H. Hsu, Eder G. Lomeli, Jaehoon Kim +9
Lithium-rich cathodes boast a large specific capacity due to the presence of excess lithium per transition metal. However, making use of that excess Li drives the cathodes to unusu…
Biaxial Strain Control of Helimagnetism via Chemical Expansion in Thin Film SrFeO3
Jennifer Fowlie, Jiarui Li, Danilo Puggioni +15
We demonstrate control of helimagnetic order in biaxially strained SrFeO3 thin films using neutron diffraction and resonant soft x-ray scattering. SrFeO3, a negative charge-transfe…
Collective Magnetic Excitations in a Photo-excited Electron-doped Cuprate Superconductor
Daniel Jost, Jiarui Li, Jordyn Hales +21
Elucidating the microscopic behavior of cuprates under ultrafast photoexcitation offers critical insights into their highly correlated out-of-equilibrium states. Although quasipart…
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…
Ab initio multiplet plus cumulant approach for correlation effects in x-ray photoelectron spectroscopy
J. J. Kas, J. J. Rehr, T. P. Devereaux
The treatment of electronic correlations in open-shell systems is among the most challenging problems of condensed matter theory. Current approximations are only partly successful.…
