Ultrafast Imaging and the Phase Problem for Inelastic X-Ray Scattering
A new method for imaging ultrafast dynamics in condensed matter using inelastic X‐ray scattering (IXS) is described. Using the concepts of causality and irreversibility a general solution to the inverse scattering problem (or “phase problem”) for IXS is illustrated, which enables direct imaging of d...
