Electronic correlations and superconducting instability in La${}_3$Ni${}_2$O${}_7$ under high pressure

Abstract

Motivated by the report of superconductivity in bilayer La${}_3$Ni${}_2$O${}_7$ at high pressure, we examine the interacting electrons in this system. First-principles many-body theory is utilized to study the normal-state electronic properties. Below 100\,K, a multi-orbital non-Fermi liquid state resulting from loss of Ni-ligand coherence within a flat-band dominated low-energy landscape is uncovered. The incoherent low-temperature Fermi surface displays strong mixing between Ni-$d_{z^2}$ and Ni-$d_{x^2-y^2}$ orbital character. In a model-Hamiltonian picture, spin fluctuations originating mostly from the Ni-$d_{z^2}$ orbital give rise to strong tendencies towards a superconducting instability with $B_{1g}$ or $B_{2g}$ order parameter. The dramatic enhancement of $T_{\mathrm{c}}$ in pressurized La${}_3$Ni${}_2$O${}_7$ is due to stronger Ni-$d_{z^2}$ correlations compared to those in the infinite-layer nickelates.
