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…
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…
Linear dichroic x-ray absorption response of Ti-Ti dimers along the axis in TiO upon Mg substitution
M. Okawa, D. Takegami, D. S. Christovam +9
Corundum oxide TiO shows the metal-insulator transition around 400-600 K accompanying the nearest Ti-Ti bond ( singlet state) formation along th…
Unusual band evolution and persistence of topological surface states in high-T_C magnetic topological insulator
K. Hori, S. Souma, C. -W. Chuang +12
Understanding the mechanism of ferromagnetism in ferromagnetic topological insulators (TIs) is a key to realize exotic time-reversal-symmetry-broken quantum phases. However, electr…
