Contrasting Spin Excitations in Octahedral and Square-Planar n=8 Ruddlesden-Popper Nickelates
K. Scott, H. LaBollita, G. A. Pan +15
The discovery of superconductivity in reduced square-planar nickelates marked a major advance in identifying structural and electronic analogs to the high- cuprates. The more…
Persistent short-range charge correlations revealed by ultrafast melting of electronic order in YBaCuO
C. Seo, L. Shen, A. N. Petsch +18
Charge density waves (CDW) are ubiquitous in the complex phase diagram of cuprate superconductors and exhibit both short- and long-range correlations. Using time-resolved resonant…
Disorder-induced damping of spin excitations in Cr-doped BaFeAs
Marli R. Cantarino, Rafael M. P. Teixeira, R. Pakuszewski +9
In doped Hund's metals, such as the iron-based superconductors, effects like charge doping and chemical pressure are often considered the dominant factors. Partial chemical substit…
Observing two-electron interactions with correlation-ARPES
A. F. Kemper, F. Goto, H. A. Labib +3
Identifying and studying the underlying two-electron interactions that give rise to emergent phenomena is a key step in developing a holistic understanding of quantum materials. Th…
