Recent discovery of superconductivity in the nickelates has ignited renewed theoretical and experimental interest in the role of electronic correlations in their properties. Here, based on in-depth first-principles and many-body perturbation theory modeling, we show that the parent (undoped) compound of the nickelate family, LaNiO 2 , hosts competing low energy phases, unlike the undoped cuprates but similar to the case of the doped cuprates. We also show the existence of flat bands near the…

Doping evolution of the Mott–Hubbard landscape in infinite-layer nickelates

State-of-the-art, locally resolved electron energy-loss spectroscopy is used to directly probe the Mott–Hubbard character of Nd1−xSrxNiO2, providing direct evidence for the multiband electronic structure of the superconducting infinite-layer nickelates.

Similarities and Differences between LaNiO2 and CaCuO2 and Implications for Superconductivity

We have revisited the electronic structure of infinite-layer RNiO$_2$ (R= La, Nd) in light of the recent discovery of superconductivity in Sr-doped NdNiO$_2$. From a comparison to their cuprate

Universal spin-glass behaviour in bulk LaNiO2, PrNiO2 and NdNiO2

Motivated by the recent discovery of superconductivity in infinite-layer nickelate thin films, we report on a synthesis and magnetization study on bulk samples of the parent compounds RNiO2 (R = La,

Dispersion of ordered stripe phases in the cuprates

A phase separation model is presented for the stripe phase of the cuprates, which allows the doping dependence of the photoemission spectra to be calculated. The idealized limit of a well-ordered

Competing stripe and magnetic phases in the cuprates from first principles

This study suggests a paradigm in which the physics of the mysterious pseudogap phase in the cuprates is encoded through a landscape of underlying competing phases in the material, showing how the landscape of competing stripe and magnetic phases can be addressed on a first-principles basis both in the parent insulator YBa2Cu3O6 and the near-optimally doped YBa 2Cu3 O7 as archetype cuprate compounds.

Electronic and magnetic structure of infinite-layer NdNiO2: trace of antiferromagnetic metal

The recent discovery of Sr-doped infinite-layer nickelate $\textrm{NdNiO}_2$ [D. Li et al. Nature 572, 624 (2019)] offers an exciting platform for investigating unconventional superconductivity in

Electronic structure of the parent compound of superconducting infinite-layer nickelates

X-ray spectroscopy and density functional theory are used to show that the electronic structure of the parent compound of superconducting infinite-layer nickelates, while similar to the copper-based high-temperature superconductors, has significant differences.

Nickelate superconductors—a renaissance of the one-band Hubbard model

The recently discovered nickelate superconductors appear, at first glance, to be even more complicated multi-orbital systems than cuprates. To identify the simplest model describing the nickelates,

Intrinsic Spin Susceptibility and Pseudogaplike Behavior in Infinite-Layer LaNiO_{2}.

The present results imply a considerable exchange interaction in infinite-layer nickelates, which sets a strong constraint for the proposed theoretical models, and unambiguously confirms a paramagnetic ground state in LaNiO_{2.

Charge density waves in infinite-layer NdNiO2 nickelates

In materials science, much effort has been devoted to the reproduction of superconductivity in chemical compositions, analogous to cuprate superconductors since their discovery over 30 years ago.
