Nearly perfect Fermi surface nesting in hole-doped LaNiO enables bulk superconductivity without pressure or strain
Chengliang Xia, Jiale Chen, Hongquan Liu +1
The discovery of high-temperature superconductivity in Ruddlesden-Popper nickelates has drawn great attention. However, unlike cuprates and iron-based superconductors, Ruddlesden-P…
Hubbard--corrected electron-phonon interactions in strongly correlated materials via the finite-displacement method
Jiale Chen, Youyou Tu, Chengliang Xia +2
Although the density functional theory plus Hubbard correction method (DFT+) is broadly used to study electronic structure of strongly correlated materials, the extension of…
Origin of local magnetic exchange interaction in infiite-layer nickelates
Yanbing Zhou, Dan Zhao, Boyun Zeng +5
Significant magnetic exchange interactions have been observed in infinite-layer nickelates RNiO2 (R = La, Pr, Nd), which exhibit unconventional superconductivity upon hole doping.…
Three-Dimensional Fermi Surface, Van Hove Singularity and Enhancement of Superconductivity in Infinite-Layer Nickelates
Chengliang Xia, Shengjie Zhou, Hanghui Chen
Recent experiments reveal a three-dimensional (3D) Fermi surface with a clear dispersion in infinite-layer nickelates, distinguishing them from their cuprate superconductor c…
