Orbital-selective d-wave superconductivity arises exclusively from the itinerant orbital in the two-band t-J model, suppressed by local inter-orbital bound states from the quasi-localized orbital.

Scalable Simulation of Strongly Correlated Electron-Phonon Systems via Non-Gaussian Matrix Product States
NGS-MPS simulations of Hubbard–Holstein models show soft phonons promote 1D phase separation and stabilize 2D stripe phases, including a novel bipolaronic stripe with enlarged unit cell.

Orbital-Selective $d$-wave Superconductivity in the Two-Band $t$-$J$ Model: Possible Applications to La$_3$Ni$_2$O$_7$
Orbital-selective d-wave superconductivity arises exclusively from the itinerant orbital in the two-band t-J model, suppressed by local inter-orbital bound states from the quasi-localized orbital.
