A coherent soft X-ray scattering view on electronic behavior in correlated materials

Abstract
In recent years, soft resonant X-ray scattering and diffraction (REXS) have contributed to the discovery of a number of electronic orderings in a variety of materials. The availability of coherent x-ray sources further added the capability of investigating their spatial inhomogeneity and collective dynamics. Effectively, this extended the sensitivity of the REXS measurements by retaining microscopic sensitivity while investigating local variation over macroscopic scales. The dream is to describe electronic orderings across the mesoscale, thus understanding material properties from quantum to classical regimes. Furthermore, at the Coherent Soft X-ray scattering beamline (CSX) of NSLS-II we proved that the mixing of time and space as realized by a highly coherent x-ray beam can be exploited in new forms, behind the expectations of traditional approaches in either of the two domains. In my talk, I will present some relevant cases, and then try to project in view of new opportunities offered by diffraction limited synchrotron sources.
