Unique Charge-density-wave Order and Fluctuation-induced Phonon Softening in the Optimally-doped Trilayer Cuprate BiSrCaCuO
S. Nakata, K. Yamamoto, J. Okamoto +11
Charge-density-wave (CDW) order is a ubiquitous feature of cuprate superconductors that competes with superconductivity. However, its behavior remains poorly understood in trilayer…
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…
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…
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…
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…
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…
Out-of-phase Plasmon Excitations in the Trilayer Cuprate BiSrCaCuO
S. Nakata, M. Bejas, J. Okamoto +14
Within a homologous series of cuprate superconductors, variations in the stacking of CuO layers influence the collective charge dynamics through the long-range Coulomb interact…
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…
