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…
Dual instability of superconductivity from oxygen defects in LaNiO
Peiheng Jiang, Jie Li, Yu-Han Cao +4
We uncover a dual mechanism by which oxygen defects suppress superconductivity in the bilayer nickelate LaNiO using density functional theory, dynamical mean-field…
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…
Dominant apical-oxygen electron-phonon coupling in HgBaCaCuO
Wenshan Hong, Qizhi Li, Shilong Zhang +14
How electron-phonon interactions influence high-temperature superconductivity in cuprates remains contested, and their role outside the CuO planes has been largely overlooked.…
