Description
What if you could see the orbitals that make a material superconducting? Superconductivity, magnetism, metal–insulator transitions: in quantum materials, everything hinges on the shape and occupation of a few electronic orbitals. Yet for decades we could only infer them, from surface-sensitive probes, indirect measurements and model-dependent analysis. This project changes that. Using X-ray Raman scattering at the SOLEIL synchrotron, we image orbitals directly, in real space, in the bulk of the crystal, and selectively for the element and orbitals we care about. Only two teams in the world can do it, and ours is one of them. You will help us image the orbitals at play in cuprates, nickelates, iron-based superconductors and Mott systems, and tackle questions at the heart of modern solid-state physics: Which orbitals carry superconductivity? How do they reorganize across a Mott transition? Is electronic nematicity an orbital order? A brand-new technique, at the frontier of experiment and theory. Read the full proposal: the orbitals are waiting to be seen.
