Superconductivity has been discovered recently in infinite-layer nickel-based 112 thin films
R 1− x A x NiO 2 (R= La, Nd, Pr and A= Sr, Ca). They are isostructural to the infinite-layer …

This article summarizes recent work on the many-body (beyond density functional theory)
electronic structure of layered rare-earth nickelates, both in the context of the materials …

Since the discovery of high-temperature superconductivity in copper oxide materials, there
have been sustained efforts to both understand the origins of this phase and discover new …

The occurrence of unconventional superconductivity in cuprates has long motivated the
search for manifestations in other layered transition metal oxides. Recently …

In materials science, much effort has been devoted to the reproduction of superconductivity
in chemical compositions, analogous to cuprate superconductors since their discovery over …

A defining signature of strongly correlated electronic systems is a rich phase diagram, which
consists of multiple broken symmetries, such as magnetism, superconductivity and charge …

The successful synthesis of superconducting infinite-layer nickelate thin films with the
highest T c≈ 15 K has ignited great enthusiasm for this material class as potential analogs …

Nickel-based superconductors provide a long-awaited experimental platform to explore
possible cuprate-like superconductivity. Despite similar crystal structure and d electron …

Topotactic transformations between related crystal structures are a powerful emerging route
for the synthesis of novel quantum materials. Whereas most such “soft chemistry” …

We review the electronic structure of nickelate superconductors with and without effects of
electronic correlations. As a minimal model, we identify the one-band Hubbard model for the …
