Pairing Mechanism in Bilayer Nickelate La${}_3$Ni${}_2$O${}_7$ Superconductors

Xianxin Wu, Tao Xiang, Jiangping Hu

The recent discovery of superconductivity with $T_c\approx 80$~K in bilayer nickelate La${}_3$Ni${}_2$O${}_7$ provides a new setting in which to test the organizing principles of unconv…
