Robust Orbital-Selective Flat Bands in Transition-Metal Oxychlorides
Xiangyu Luo, Ludovica Zullo, Sahaj Patel +10
Flat electronic bands, which amplify electron correlations by quenching kinetic energy, provide an ideal foundation for exotic quantum phases. However, prevailing strategies -- inc…
Structural origin of resonant diffraction in RuO
Connor A Occhialini, Christie Nelson, Alessandro Bombardi +12
We report Ru L-edge resonant X-ray diffraction studies on single crystal and (001) epitaxial films of RuO. We investigate the distinct and refl…
Electrical switching of an unconventional odd parity magnet
Qian Song, Srdjan Stavrić, Paolo Barone +11
Magnetic states with zero magnetization but non-relativistic spin splitting are outstanding candidates for the next generation of spintronic devices. Their electron-volt (eV) scale…
Higgs-mode electromagnon in the spin-spiral multiferroic CuBr
Bryan T. Fichera, Ajesh Kumar, Baiqing Lv +8
Below a continuous symmetry breaking phase transition, the relevant collective excitations are due to longitudinal and transverse fluctuations of the order parameter, which are ref…
Spin-forbidden excitations in the magneto-optical spectra of CrI tuned by covalency
Connor A. Occhialini, Luca Nessi, Luiz G. P. Martins +10
Spin-forbidden () multiplet excitations and their coupling to magnetic properties are of increasing importance for magneto-optical studies of correlated materials. Nonet…
Uncovering the Hidden Ferroaxial Density Wave as the Origin of the Axial Higgs Mode in RTe
Birender Singh, Grant McNamara, Kyung-Mo Kim +24
The recent discovery of an axial amplitude (Higgs) mode in the long-studied charge density wave (CDW) systems GdTe and LaTe suggests a heretofore unidentified hidden order.…
Nature of excitons and their ligand-mediated delocalization in nickel dihalide charge-transfer insulators
Connor A. Occhialini, Yi Tseng, Hebatalla Elnaggar +7
The fundamental optical excitations of correlated transition-metal compounds are typically identified with multielectronic transitions localized at the transition-metal site, such…
Infrared Optical Anisotropy in Quasi-1D Hexagonal Chalcogenide BaTiSe3
Boyang Zhao, Hongyan Mei, Zhengyu Du +9
Polarimetric infrared detection bolsters IR thermography by leveraging the polarization of light. Optical anisotropy, i.e., birefringence and dichroism, can be leveraged to achieve…
Anomalous Antiferromagnetism in Metallic RuO Determined by Resonant X-ray Scattering
Z. H. Zhu, J. Strempfer, R. R. Rao +7
We studied the magnetic ordering of thin films and bulk crystals of rutile RuO using resonant X-ray scattering across the Ru L absorption edge. Combining polarization analy…
