Orbital-Selective $d$-wave Superconductivity in the Two-Band $t$-$J$ Model: Possible Applications to La${}_3$Ni${}_2$O${}_7$

Zhan Wang, Kun Jiang, Fu-Chun Zhang +1

We investigate superconductivity in a two-band $t$-$J$ model consisting of an itinerant orbital (orbital-0) and a quasi-localized orbital (orbital-1) using variational Monte Carlo.…
