The physical description of all materials is rooted in quantum mechanics, which describes
how atoms bond and electrons interact at a fundamental level. Although these quantum …

Resonant inelastic X-ray scattering (RIXS) is a powerful technique that combines
spectroscopy and inelastic scattering to probe the electronic structure of materials. RIXS is …

The discovery of superconductivity in infinite-layer nickelates brings us tantalizingly close to
a material class that mirrors the cuprate superconductors. We measured the magnetic …

In the past decade, resonant inelastic x-ray scattering (RIXS) has made remarkable progress
as a spectroscopic technique. This is a direct result of the availability of high-brilliance …

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 …

The recent discovery of superconductivity in oxygen-reduced monovalent nickelates has
