Orbital and Spin Character of Doped Carriers in Infinite-Layer Nickelates
M. Rossi, H. Lu, A. Nag +13
The recent discovery of superconductivity in NdSrNiO has drawn significant attention in the field. A key open question regards the evolution of the electronic str…
Coulombically-stabilized oxygen hole polarons enable fully reversible oxygen redox
Iwnetim I. Abate, C. Das Pemmaraju, Se Young Kim +10
Stabilizing high-valent redox couples and exotic electronic states necessitate an understanding of the stabilization mechanism. In oxides, whether they are being considered for ene…
Spectroscopic Evidence for Charge Order Melting via Quantum Fluctuations in a Cuprate
W. S. Lee, K. J. Zhou, M. Hepting +14
Copper-oxide high TC superconductors possess a number of exotic orders co-existing with or proximal to superconductivity, whose quantum fluctuations may account for the unusual beh…
Observing photo-induced chiral edge states of graphene nanoribbons in pump-probe spectroscopies
Yuan Chen, Yao Wang, Martin Claassen +2
Photo-induced edge states in low dimensional materials have attracted considerable attention due to the tunability of topological properties and dispersion. Specifically, graphene…
Electronic Structure Trends Across the Rare-Earth Series in Superconducting Infinite Layer Nickelates
Emily Been, Wei-Sheng Lee, Harold Y. Hwang +5
The recent discovery of superconductivity in oxygen-reduced monovalent nickelates has raised a new platform for the study of unconventional superconductivity, with similarities and…
DC Hall coefficient of the strongly correlated Hubbard model
Wen O. Wang, Jixun K. Ding, Brian Moritz +2
The Hall coefficient is related to the effective carrier density and Fermi surface topology in noninteracting and weakly interacting systems. In strongly correlated systems, the re…
