Theoretical study of superconductivity in freestanding infinite-layer nickelate membranes under pressure: mitigation of excess correlation enhances $T_c$

Mahiru Seki, Reo Kono, Naotaka Tanaka +5

We theoretically investigate a freestanding membrane of infinite-layer nickelate Nd${}_{0.85}$Sr${}_{0.15}$NiO${}_2$ under pressure by constructing a seven-orbital effective model based…
