An overview of both experimental and theoretical results in the field of resonant scattering of
tunable soft and hard x-ray radiation is presented, with a main focus on the closely related …

Collective excitations of bound electron-hole pairs—known as excitons—are ubiquitous in
condensed matter, emerging in systems as diverse as band semiconductors, molecular …

This Perspective addresses the design, creation, characterization and control of synthetic
quantum materials with strong electronic correlations. We show how emerging synergies …

This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The
aim is to provide newcomers to the area with insights into: the basic physics of FELs, the …

Understanding quantum materials—solids in which interactions among constituent electrons
yield a great variety of novel emergent quantum phenomena—is a forefront challenge in …
