Pair-density-wave superconductivity and Anderson's theorem in bilayer nickelates
Hanbit Oh, Ya-Hui Zhang
The recent experimental observations of high temperature superconductivity in bilayer nickelate have attracted lots of attentions. Previous studies have assumed a mirror symmetry $…
Magnetism and superconductivity in bilayer nickelate
Hui Yang, Ya-Hui Zhang
The discovery of high-temperature superconductivity in bilayer nickelate LaNiO necessitates a minimal theoretical model that unifies the superconducting phase wit…
Doping a spin-one Mott insulator: possible application to bilayer nickelate
Hanbit Oh, Hui Yang, Ya-Hui Zhang
In this article, we review some recent theoretical developments on potential high-temperature superconductors and unconventional metallic states that can arise from doping a spin-o…
High spin, low spin or gapped spins: magnetism in the bilayer nickelates
Hanbit Oh, Yi-Ming Wu, Julian May-Mann +4
Inspired by the recent discovery of high-temperature superconductivity in bilayer nickelates, we investigate the role of magnetism emerging from a hypothetical insulating par…
