Phase coexistence during a solid-to-solid transition in a quantum material is measured using x-ray coherent diffractive imaging.
Solid-state systems can host a variety of thermodynamic phases that can be controlled with magnetic fields, strain,

Snapshots of a phase transition Time-resolved x-ray scattering can be used to investigate the dynamics of materials during the switch from one structural phase to another. So far, methods provide an ensemble average and may miss crucial aspects of th

In our original Letter, we used spectral holography to identify the growth of metallic domains in insulating VO2. In this work, we identified three phases based on spectroscopy: M1, M2, and R. However, spectroscopy based on the holographic method, as
