Jahn-Teller distortion on strained LaNiO thin films
Yuxin Wang, Zhan Wang, Fu-Chun Zhang +1
We present a systematic study of the electronic structure of strained LaNiO thin films. We show that biaxial compressive strain mainly elongates the outer apical Ni-O b…

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…
