@conference{Son20a, author={Sang-Kil Son}, title={Breakdown of frustrated absorption in x-ray sequential multiphoton ionization}, year={2020}, month={April 1}, booktitle={CFEL-DESY Theory Seminar}, organization={CFEL}, institution={DESY}, address={Hamburg, Germany}, keywords={XATOM; frustrated absorption; soft x-ray; x-ray multiphoton ionization; REXMI; Xe; XFEL; European XFEL; CFEL; DESY;}, note={oral presentation}, abstract={When intensity of ionizing radiation increases, would ionization increase or decrease? It is not a trifling question, when the radiation comes from x-ray free-electron lasers (XFELs). If higher intensity is attained by shrinking the pulse duration, it turns out that the higher the intensity, the less the ionization. This counterintuitive behavior, so-called frustrated absorption or intensity-induced x-ray transparency, has been regarded as one of the fundamental aspects in the XFEL--matter interaction and has been widely applied for successful XFEL experiments. However, the paradigm of frustrated absorption can break down at extremely high intensity. In this talk, I will present when and how the breakdown of frustrated absorption happens. Also I will discuss implication of this novel pulse-duration dependence of x-ray multiphoton ionization in recent European XFEL SQS experiment.} }
