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…
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…

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…
Random Fields from Quenched Disorder in an Archetype for Correlated Electrons: the Parallel Spin Stripe Phase of LaNdSrCuO at the 1/8 Anomaly
Q. Chen, S. H. -Y. Huang, Q. Ma +5
The parallel stripe phase is remarkable both in its own right, and in relation to the other phases it co-exists with. Its inhomogeneous nature makes such states susceptible to rand…
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…
Quantum fluctuations of charge order induce phonon softening in a superconducting cuprate
H. Y. Huang, A. Singh, C. Y. Mou +13
Quantum phase transitions play an important role in shaping the phase diagram of high-temperature cuprate superconductors. These cuprates possess intertwined orders which interact…

A. Singh, H. Y. Huang, Y. Y. Chu +18
We report on the development of a high-resolution and highly efficient beamline for soft-X-ray resonant inelastic X-ray scattering (RIXS) located at Taiwan Photon Source. This beam…
Acoustic plasmons and conducting carriers in hole-doped cuprate superconductors
