Bi-altermagnetism unveiled 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…
Interlayer hybridization enables superconductivity in bilayer nickelates
Shilong Zhang, Meng Zhang, Qilin Luo +10
Ruddlesden-Popper nickelates offer a new route to high-temperature superconductivity beyond the cuprates and iron-pnictides. However, the electronic reorganization that enables sup…
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…
Non-reciprocal circular dichroism of axial phonons coupled to ferro-rotational order
H. Y. Huang, G. Channagowdra, D. Banerjee +10
Circular dichroism (CD) in X-ray absorption, defined as the difference in absorption between opposite circular polarizations, is fundamentally enabled by the breaking of time-rever…
Altermagnetic boosting of chiral phonons
J. Okamoto, C. Y. Mou, H. Y. Huang +10
Chirality characterizes the asymmetry between a structure and its mirror image and underlies a wide range of chiral functionalities. In crystallographically chiral materials, phono…
Spin Excitations and Flat Electronic Bands in a Cr-based Kagome Superconductor
Zehao Wang, Yucheng Guo, Hsiao Yu Huang +33
In the quest for topology- and correlation-driven quantum states, kagome lattice materials have garnered significant interest for their band structures, featuring flat bands (FBs)…
