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…
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…
