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…
Interlayer hybridization enables superconductivity in bilayer nickelates
Shilong Zhang, Meng Zhang, Qilin Luo +10
Ruddlesden-Popper nickelates offer a new route to high-temperature superconductivity beyond the cuprates and iron-pnictides. However, the electronic reorganization that enables sup…
Altermagnetism and Room-Temperature Metal-to-Insulator Transition in CsCrSO
Yi Liu, Chen-Chao Xu, Jin-Ke Bao +14
Metal-to-insulator transitions (MITs), particularly near room temperature, have been extensively studied in nonmagnetic and conventional ferromagnetic and antiferromagnetic systems…
Dissecting superconductivity in the Ruddlesden-Popper nickelates: The role of electron correlation and interlayer magnetic exchange
Xiaoyang Chen, Zezhong Li, Mei Xie +9
The discovery of superconductivity in the Ruddlesden-Popper (RP) nickelates has opened a new chapter in the search for high superconducting transition temperatures ()…
Highly Anisotropic Charge Dynamics and Spectral Weight Redistribution in the Trilayer Nickelate LaNiO
Zhe Liu, Jie Li, Deyuan Hu +10
We study the -plane and -axis charge dynamics of LaNiO using optical spectroscopy. While a pronounced Drude profile, i.e. metallic response, is observed i…
Distinct orbital contributions to electronic and magnetic structures in LaNiO
Shilong Zhang, Hengyuang Zhang, Zehao Dong +10
High-T superconductivity has recently been discovered in Ruddlesden-Popper phase nickelates under pressure, where the low-energy electronic structure is dominated by Ni $d_{x^2…
