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…
