Orbital-specific Itinerancy and Localization in a Kagome Magnet
S. V. Streltsov, H. Y. Huang, A. Ushakov +10
The kagome lattice naturally hosts flat bands, Dirac fermions, and van Hove singularities, yet whether its geometry can stabilize orbital-selective phases - a hallmark of Hund's ph…
Quantum critical behavior of cuprate superconductors observed by inelastic X-ray scattering
H. Y. Huang, C. Y. Mou, A. Singh +7
Progress toward a complete understanding of cuprate superconductors has been hindered by their intricate phase diagram, potentially linked to a quantum critical point (QCP). Howeve…
Signatures of bi-altermagnetism revealed by sublattice-specific circular dichroism in resonant inelastic X-ray scattering
G. Channagowdra, A. Singh, H. Y. Huang +9
An altermagnet is a recently identified class of magnets that exhibit a zero net magnetic moment but break symmetry under the combined operations of parity and time reversal. It ty…
Bimagnon dispersion of La2CuO4 probed by resonant inelastic X-ray scattering
A. Singh, H. Y. Huang, K. Tsutsui +6
We report on the study of the magnetic excitations of Mott insulator La2CuO4 by using resonant inelastic x-ray scattering (RIXS) and cluster calculations within the framework of ex…
Spin-orbit-entangled electronic structure of BaCaOsO studied by O -edge resonant inelastic X-ray scattering
J. Okamoto, G. Shibata, Yu. S. Posonov +9
Transition-metal ions with electronic configuration in a cubic crystal field are prone to have a vanishing dipolar magnetic moment but finite higher-order multipolar moments…
Exciton dynamics uncovering electron fractionalization in superconducting cuprates
A. Singh, H. Y. Huang, J. D. Xie +6
Electron quasiparticles play a crucial role in simplifying the description of many-body physics in solids with surprising success. Conventional Landau's Fermi-liquid and quasiparti…
Acoustic plasmons and conducting carriers in hole-doped cuprate superconductors
A. Singh, H. Y. Huang, Christopher Lane +8
The superconductivity of cuprates, which has been a mystery ever since its discovery decades ago, is created through doping electrons or holes into a Mott insulator. There, however…
Evolution of valence-specific spin states and local distortions in LaSrCoO
J. Okamoto, A. Chainani, Z. Y. Chen +7
We present X-ray spectroscopic evidence for the evolution of valence-specific spin states and tetragonal distortions in single-layer cobaltates. Measurements of Co -edge reson…
