  • The underlying mechanism behind charge density wave formation in Kagome metals is still not fully understood. Here, the authors propose that the phonon modes become frustrated in the charge density wave phase of CsV3Sb5.

  • The intermediate states in photo-excited phase transitions are expected to be inhomogeneous. However, ultrafast X-ray imaging shows the early part of the metal–insulator transition in VO2 is homogeneous but then becomes heterogeneous.

  • Pump–probe measurements conventionally achieve femtosecond time resolution for X-ray crystallography of reactive processes, but the measured structural dynamics are complex. Using coherent control techniques, we show that the ultrafast crystallographic differences of a fluorescent protein are dominated by ground-state vibrational processes that are unconnected to the photoisomerization reaction of the chromophore.
