Filling and Interlayer Superexchange Control Superconductivity in La${}_3$Ni${}_2$O${}_7$

Zeyu Chen, Jia-Heng Ji, Yu-Bo Liu +2

The paper proposes that superconducting transition temperature in bilayer nickelate La₃Ni₂O₇ is controlled by the d_{x²‑y²} orbital filling and the interlayer antiferromagnetic sup…
