  • Warm dense copper, created by an X-ray free-electron laser, features a transition from reverse saturable absorption to saturable absorption. The results can be used to benchmark non-equilibrium models of electronic structure in warm dense matter.

  • X-ray free electron lasers allow for studying the interaction of magnetic materials with intense X-rays beyond a linear response regime. Here, the authors demonstrate the onset of X-ray induced ultrafast demagnetization in Co/Pd multilayers via a redistribution of valence electrons on timescales shorter than 40 fs.
