Collective spin excitations in trilayer nickelate LaNiO
Ying Chan, Yuehong Li, Yujie Yan +14
Ruddlesden-Popper (RP) nickelates have recently emerged as a new family of high-temperature superconductors. In bilayer RP nickelates, magnetic excitations with large exchange coup…

Contrasting Momentum-Selective Spin-Density-Wave Gaps in Bilayer and Trilayer Nickelates
Jun Shu, Jun Shen, Xiaoxiang Zhou +12
Resolving where the density-wave gap opens in momentum space is essential for identifying the microscopic origin of the instability in layered nickelates. Using polarization-resolv…

Direct Observation of Unidirectional Density Wave and Band splitting in a Single-Domain Trilayer Nickelate PrNiO
Zhicheng Jiang, Enkang Zhang, Yuxin Wang +12
Unraveling the interplay between density-wave (DW) instabilities and multi-orbital physics is critical for understanding superconductivity in Ruddlesden-Popper nickelates, yet intr…
