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…
Percolative Pathway to Stripe Order in KTaO3-Based Superconductivity
Zhihao Chen, Chun Sum Brian Pang, Meng Yang +8
The sensitivity of low dimensional superconductors to fluctuations gives rise to emergent behaviors beyond the conventional Bardeen Cooper Schrieffer framework. Anisotropy is one s…
Low-temperature mean valence of nickel ions in pressurized LaNiO
Shu Cai, Yazhou Zhou, Hualei Sun +18
The discovery of high critical temperature (Tc) superconductivity in pressurized LaNiO has ignited renewed excitement in the search of novel high-Tc superconducting com…
Bulk high-temperature superconductivity in the high-pressure tetragonal phase of bilayer La2PrNi2O7
Ningning Wang, Gang Wang, Xiaoling Shen +26
The Ruddlesden-Popper (R-P) bilayer nickelate, La3Ni2O7, was recently found to show signatures of high-temperature superconductivity (HTSC) at pressures above 14 GPa. Subsequent in…
