Unconventional Pressure Evolution of Spin-Density-Wave State in LaNiO
Xiaoxiang Zhou, Shiyu Xie, Liangxin Qiao +13
The discovery of pressure-induced high temperature superconductivity in the bilayer nickelate LaNiO has raised the question of how its spin-density-wave (SDW) sta…
orbital delocalization and magnetic collapse in superconducting (La,Pr)NiO films
Xiaoyang Chen, Wenliang Zhang, Fei Peng +20
The recent discovery of Ruddlesden--Popper (RP) nickelate thin-film superconductors has opened a new frontier in unconventional superconductivity. Its realization requires both com…
Anisotropic Electronic Correlations in the Spin Density Wave State of LaNiO
Ge He, Jun Shen, Shiyu Xie +21
The bilayer nickelate superconductor LaNiO undergoes a density wave transition near 150 K that has attracted intensive scrutiny, yet its microscopic origin remains elus…
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…
Yin-Yang vortex on UTe2 (011) surface
Ruotong Yin, Yuanji Li, Zengyi Du +14
UTe2 is a promising candidate for spin-triplet superconductor, yet its exact superconducting order parameter remains highly debated. Here, via scanning tunneling microscopy/spectro…
