Transitions in matter triggered by intense ultrashort X-ray pulses
Beata Ziaja, Zoltan Jurek, Nikita Medvedev, Sang-Kil Son, Robert Thiele, and Robin Santra55th Annual Meeting of the APS Division of Plasma Physics
(American Physical Society, Denver, Colorado, November 11-15, 2013)
In my talk I will give an overview on the recent results of our theoretical investigation how the unique properties of X-ray free-electron laser (FEL) radiation can be employed to modify extended atomic or molecular assemblies, and to create new states of matter. I will discuss three topics that are related to various irradiation regimes that can be achieved, depending on the FEL pulse fluence: (i) atomic processes within laser-created plasmas, (ii) ultrafast electron kinetics in irradiated semiconductors, and (iii) radiation-induced structural changes in solids.
