Electronic structure trends in LaNiO ( Pr, Nd, Sm) from first-principles
Yi-Feng Zhao, Antia S. Botana
The discovery of superconductivity in bilayer LaNiO under pressure has sparked tremendous attention on Ruddlesden-Popper (RP) nickelates. Recently, a higher superconduc…
Electron vs. hole doping in infinite-layer nickelates: electronic structure, magnetism and correlations
Ezra Day-Roberts, Fabio Bernardini, Harrison LaBollita +3
The observation of superconductivity in undoped infinite-layer nickelates NiO ( = rare earth) challenges our current understanding and calls for a re-examination of the u…
Pressure and strain tuning of the alternating bilayer-trilayer Ruddlesden-Popper nickelate: crystal and electronic structure
Huan Wu, Yi-Feng Zhao, Antia S. Botana
We use first-principles calculations to investigate the crystal and electronic structure of the hybrid bilayer-trilayer Ruddlesden-Popper (RP) nickelate LaNiO under…
Structural stability, electronic structure, and magnetic properties of the single-layer trilayer La3Ni2O7 polymorph
Shekhar Sharma, Yi-Feng Zhao, Antia S. Botana
A polymorph of the bilayer nickelate La3Ni2O7 that displays an alternating single-layer (SL) and trilayer (TL; 1313) stacking pattern has recently been discovered. Signatures of su…
Electronic layer decoupling driven by density-wave order in LaNiO
Ziqiang Guan, Sophia F. R. TenHuisen, M. Tepie +14
We probe the density-wave transition of the trilayer nickelate LaNiO with polarization-resolved infrared spectroscopy. The low-energy electrodynamics is strongly ani…
Role of correlations in Ruddlesden-Popper bilayer nickelates under compressive strain
Logan Bleys, Nicholas Corkill, Yi-Feng Zhao +4
The recent discovery of superconductivity in thin films of the bilayer Ruddlesden-Popper (RP) nickelate LaNiO (La327) under compressive strain has generated enormous in…
